FIBA/U.S. Rule Differences
Revised 2008-05-04
(includes information referred to on my Rule Changes page)
Basketball is played all around the world using the same set of rules... except in North America, of course!
Below is a list of major rule differences between FIBA (International) Rules and many of those used in North America. The list is meant to give more detailed information than some other comparisons (more suitable for usage by referees), but is by no means exhaustive.
Each point listed will address the following sets of rules:
| FIBA | International Rules |
| NBA | National Basketball Association, the world's premier professional league, with teams in the United States and Canada. |
| WNBA | A professional women's summer league founded by the NBA in 1997. |
| NCAA Men | US National Collegiate Athletic Association. There are some rule variations between Men and Women's rules. |
| NCAA Women |
| CIS Men 2006 | A variant of NCAA Men's Rules used by Canadian Interuniversity Sport until the change to FIBA in Fall 2007. |
| CIS Women 2006 | A cross between FIBA Rules and NCAA Men's Rules used by Canadian Interuniversity Sport for women's play prior to Fall 2007 (FIBA is now used without modification). |
The CBA (Continental Basketball Association) and NBDL (the NBA's fall development league) uses rules identical to the NBA for purposes of this discussion.
I do not have current information on US High School rules (National Federation rules), so I have chosen to omit them. They are similar in philosophy to NCAA Men's rules, but they have some peculiar quirks. The NCAA also puts a comparison in the back of their rule book each year, which is available online. Check some of the sources listed in my Hoop Links for more current information on NF Rules.
A reminder that this page is ©2000–2008 Anthony Reimer. If you want to reproduce this handout (for a clinic, for instance), you need to seek permission from me. In many cases, there will be no royalty charged so long as proper recognition is given.
Major Differences
Three Point Line (measured from the centre of the basket)
| FIBA | 6.25 m (20' 6.25") |
| NBA | an arc of 23'9" (7.24 m), which intersects with lines parallel to the sideline which are 22' (6.7 m) away at their closest point to the basket |
| WNBA | 20' 6.25" (6.25 m) |
| NCAA Men | 19'9" (6.02 m), increasing to 20'9" (6.325 m) for 2008–09 season |
| NCAA Women | 19'9" (6.02 m) |
| CIS Men 2006 | 6.25 m (approx. 20' 6.25") |
| CIS Women 2006 |
Restricted Area (a.k.a. "The Key" or "The Lane")

| CIS Women 2006 | A trapezoid 3.6 m (12') wide at the free throw line and 6 m wide (19' 8.25") at the baseline |
Playing Time
| FIBA | 4 - 10 minute quarters; OT periods are 5 min each |
| NBA | 4 - 12 minute quarters; OT periods are 5 min each |
| WNBA | 4 - 10 minute quarters; OT periods are 5 min each |
| NCAA Men | 2 - 20 minute halves; OT periods are 5 min each |
| NCAA Women |
| CIS Men 2006 | 2 - 20 minute halves; OT periods are 5 min each |
| CIS Women 2006 |
Game Clock Operation — Last Minutes of Play/Field Goal
The clock stops after a successful field goal...
| FIBA | In the last two minutes of the second half and any OT period |
| NBA | In last minute of quarters 1, 2, 3, last 2 minutes of quarter 4 and any OT |
| WNBA | In last minute of every period |
| NCAA Men | In the last minute of the second half and any OT period |
| NCAA Women |
| CIS Men 2006 | In the last minute of the second half and any OT period |
| CIS Women 2006 |
Shot Clock — Time Allowed to Shoot
Shot Clock — Operation
All rules agree that a team must attempt (release) a shot before the clock expires and that for it to be a legal attempt, the ball must strike the ring. After a legal attempt, the clock is reset to its maximum value and does not start again until a team gains control (or is awarded possession for a throw-in). Likewise, a change of team control causes the shot clock to be reset. Shot clocks are stopped when play stops. Clocks are never reset when a defensive player causes the ball to go out of bounds (the word "violation" used below does not refer to out-of-bounds violations). The rules diverge on which situations cause a reset, how much that reset will be, and when the clock will restart.
| FIBA | - In cases where play resumes with less than full amount on shot clock, shot clock does not resume until team establishes control in bounds.
- The shot clock is reset after most fouls (personal or technical) — exceptions follow.
- The shot clock is not reset on a double foul or alternating possession situation when the same team retains possession.
|
| NBA | - When play resumes with less than full amount on shot clock, shot clock resumes with first touch in bounds
- Changed in 2007–08: The shot clock is reset to 24, 14, or 5 (unless the time remaining on the clock is greater) under the following circumstances:
- Reset to 24 on all flagrant and punching fouls, as well as personal fouls and violations resulting in a backcourt throw-in.
- Reset to 14 on personal fouls and defensive 3-second or kicked/punched ball or jump ball situation (no change of possession) violations resulting in a front court throw-in; a defensive technincal foul or delay of game warning; an infection control situation
- Reset to 5 when the same team retains possession on a jump ball situation resulting from a defensive tie-up.
- The shot clock is not reset when the offensive team commits a technical foul or is charged with a delay of game warning
|
| WNBA |
| NCAA Men | - When play resumes with less than full amount on shot clock, shot clock resumes with first touch in bounds
- The shot clock is reset after most fouls (personal or technical) — exceptions follow.
- The shot clock is not reset on a double foul or alternating possession situation when the same team retains possession.
- The shot clock is not reset when the offensive team commits a technical foul.
- For kicked ball violations, if the violation occurs with 14 or fewer seconds remaining on the shot clock, it shall be reset to 15 seconds. Otherwise, there shall be no reset (the time remaining shall be used).

| NCAA Women |
| CIS Men 2006 | Same as NCAA |
| CIS Women 2006 |
Time Outs — Number and Duration
| FIBA | - 2 time outs in first half, 3 in second half, one per overtime period
- All time-outs must last 60 seconds
- Time-outs do not accumulate
|
| NBA | - 6 "regular" time outs per regulation time (with some restrictions — some mandatory timeouts for TV are built into the 6), 2 regular timeouts per overtime period
- Regular time outs are 60 seconds in duration, except the first two timeouts in each period and the extra mandatory timeout in Quarters 2 and 4, which are 100 seconds
- Time outs do not accumulate into overtime
- One 20 second timeout per half and each overtime period.
- Maxiumum 3 regular timeouts in the fourth period.
- New in 2007–08: If a team has 2 or 3 regular timeouts remaining when the fourth period or overtime period reaches the 2:00 mark, those will change to one regular timeout and one 20-second timeout. (Thus, a team may never have more than 1 regular and two 20-second timeouts in the last two minutes of a game.)
|
| WNBA | - 2 "regular" timeouts per half (one of those timeouts will generally be charged as a mandatory timeout), 1 per overtime period
- The first regular timeout in the first and third period and the first two regular timeouts in the second and fourth period are 120 seconds in length. All other regular timeouts are 60 seconds in length.
- Unused regular time outs do not accumulate from half to half, nor into overtime
- One 20 sec timeout in each half and OT period; can carry one over from 1st to 2nd Half or 2nd Half to OT (never more than two allowed in OT period).
|
| NCAA Men | Electronic Media Game: - 4 30-second time outs and 1 60-second time out per game
- A maximum of 3 30-second time outs and one 60-second time out may be carried into the second half
- One additional 30-second time out is added per overtime period (any timeouts remaining from the second half may be carried over into overtime)
- First 30-second time out of the second half is extended to the length of a media timeout.
- If coach requests 2 consecutive 30-second timeouts, players may sit on the bench, so long as the request is made when the first timeout is granted. (Normally, players must remain standing and on the floor during a 30-second timeout.)
- Time outs that are not Electronic Media timeouts may be shortened.
Non-E.M. Game: - 4 "full" time outs per game (75 seconds, warning horn after 60 seconds has expired), add one per overtime
- 2 - 30 sec timeouts per game (can be used any time)
- All time outs are cumulative
|
| NCAA Women |
| CIS Men 2006 | same as NCAA Men Non-E.M. Game (some conferences may adopt altered rules for conference play only) |
| CIS Women 2006 | same as FIBA |
Time Outs — How To Call, When Allowed, Privileges
| FIBA | - Must be called by the coach through the scorer's table
- Time out granted on next stoppage or, if asked for in time, after the next field goal scored against (a mercy rule of sorts).
- No time-outs granted once a set of free throws has started — Exceptions: If the last free throw is successful, the team scored upon may be granted a timeout; if the free throw is followed by possession at centre, either team may be granted a timeout before the throw-in.
- Ball is advanced to centre in the last two minutes of the 4th quarter (or OT) when a timeout is called by the team with the ball entitled to a throw-in in the back court (including after a successful field goal by the opponents).
|
| NBA | - Called from the floor by players anytime a player on their team is in control of the ball, or whenever the ball is dead (once you are scored upon, you are deemed to be in control, so no time-outs after you score a basket as is possible in the NCAA)
- The Head Coach may also request a time-out from an official.
- A player may not call timeout if both of his/her feet are in the air and any part of his/her body has broken the vertical plane of the sideline, baseline, or midcourt line
- Ball may be advanced to front court (the 28' line, in specific) in some situations after calling a full or 20 second time out late in the game
|
| WNBA |
| NCAA Men | - Called from the floor by players or the coach anytime a player on their team is in control of the ball, or whenever the ball is dead, including after a field goal or free throw scored by either team.
- A time out shall not be recognized if an airborne player's momentum carries them out of bounds or into the back court.
|
| NCAA Women |
| CIS Men 2006 | Same as NCAA |
| CIS Women 2006 |
Jump Ball, Held Ball, Alternating Possession
| FIBA | - On all held ball/jump ball situations during the game (including the beginning of most periods), teams alternate receiving the ball ("alternating possession"), with the team not gaining possession of the initial (tossed) jump ball being the first recipient.
- First half begins with a jump ball; alternating possession at the beginning of all other periods.
- The shot clock shall not be reset if the offensive team retains possession of the ball through the alternating process.
|
| NBA | - On all held ball/jump ball situations during the game, play resumes with a (tossed) jump ball
- If the offence retains possession after a jump ball, the clock is reset to 5 seconds (new in 2007–08) or remains the same if there were more than 14 seconds on the clock. If the defense commits a violation during the jump ball, the clock is reset to 14. If the defense gains possession, the clock is reset to 24 seconds.
- First period and any overtime begin with a jump ball; periods 2, 3, and 4 start with possession based on team winning opening tip (2 and 3 to loser of tip, 4 to winner). New in 2007–08: Throw-in is treated like a throw-in after a successful basket (player may run baseline and/or pass to teammates out of bounds).
|
| WNBA |
| NCAA Men | - On all held ball/jump ball situations during the game (including the start of the second half), teams alternate receiving the ball ("alternating possession"), with the team not gaining possession of the last (tossed) jump ball being the first recipient
- The game and any overtime period start with a jump ball; alternating possession at the beginning of the second half
- If the offensive team retains the ball due to the alternating process, the shot clock shall not be reset.
|
| NCAA Women |
| CIS Men 2006 | Same as NCAA |
| CIS Women 2006 |
Substitutions
| FIBA | - A "substitution opportunity" begins when the clock is stopped and the ball is dead (i.e. after a whistle or after a field goal in the last two minutes). It ends when an official steps into the circle to toss a jump ball or an official steps into the lane to administer free throw(s) or the ball is at the disposal of a player for a throw-in. One major effect of this is to disallow subs between free throws.
- Either team may sub on any foul, jump ball, time out or [new in 2004] violation that creates a substitution opportunity.
- If the last free throw is successful (or is followed by possession at centre), either team may substitute (limitations regarding subs for the shooter have been eliminated; now similar to NCAA).
- After a basket in the last two minutes, the team scored upon may initiate a substitution (the player(s) must be there before the basket is scored). If only the team that scores wants the substitution, it shall not be allowed.
- Referee's stoppages are explicitly included as substitution opportunities for either or both teams.
|
| NBA | - Subs permitted by either team when the clock is stopped and the ball is dead. Exception: Subs not permitted after a successful final free throw or field goal (in the final minute(s) of a period). In many cases, the player must be in the 8' box (near the centre of the scorer's table) at the time of the stoppage in order to come into the game.
- Subs are not allowed during a referee's stoppage (e.g., delay of game warning, stopping play due to an errant ball).
- During free throw activity, subs are permitted after the first free throw in a multiple throw penalty, but not thereafter (i.e. not between the second and third throws, nor after a successful final throw). "Sub for the shooter" is not generally permitted.
|
| WNBA |
| NCAA Men | - Subs by either team permitted when the clock is stopped and the ball is dead, including after a successful free throw. Exception: Substitutions shall not be permitted in the last 59.9 seconds of the second half or any extra period when the clock is stopped (a) due to a successful field goal, (b) to correct a timer's mistake, or (c) due to an inadvertent whistle.
- No restrictions on which team must initiate subs, even after a successful final free throw.
- In situations where two or three free throws are awarded, substitutions are held until just prior to the final throw.
|
| NCAA Women |
| CIS Men 2006 | - Subs by either team permitted when the clock is stopped and the ball is dead, including after a successful free throw. Exception: Substitutions shall not be permitted in the last 59.9 seconds of the second half or any extra period when the clock is stopped (a) due to a successful field goal, (b) to correct a timer's mistake, or (c) due to an inadvertent whistle.
- No restrictions on which team must initiate subs, even after a successful final free throw.
- Substitutions are allowed at the beginning of and between free throws.
|
| CIS Women 2006 | - Subs by either team permitted when the clock is stopped and the ball is dead, including after a successful free throw. Exception: Substitutions shall not be permitted in the last 59.9 seconds of the second half or any extra period when the clock is stopped (a) due to a successful field goal, (b) to correct a timer's mistake, or (c) due to an inadvertent whistle.
- On a violation where a team is awarded a non-handled throw-in in their backcourt, only that team may initiate a substitution (similar to the pre-1990 FIBA rule).
- Substitutions are allowed at the beginning of and between free throws.
|
Player Fouls
| FIBA | - Foul out on 5 (personal + technical)
- All fouls involving contact with an opponent, even when play is stopped, are personal fouls
|
| NBA | - Foul out on 6 personal or 2 technical fouls
- Fouls committed while the ball is dead are technical fouls.
|
| WNBA |
| NCAA Men | - Foul out on 5 (personal fouls + non-administrative technical fouls)
- Fouls committed while the ball is dead are technical fouls.
|
| NCAA Women |
| CIS Men 2006 | Same as NCAA |
| CIS Women 2006 |
Team Fouls (Penalty or "Bonus" Free Throws)
Note: In all rules, if a shooting foul occurs, or any other foul that would lead to free throws regardless of the foul count, the normal penalty shall supersede any penalty related to foul count.
| FIBA | - Penalty (2 shots) is awarded on any team foul after the 4th of each quarter (i.e. on the 5th) unless the foul is an offensive foul; overtime is an extension of the 4th quarter.
- Team fouls include all personal fouls and player (not coach) technical fouls.
|
| NBA | - Penalty (a total of 2 shots) is awarded on the 5th team foul in each quarter (on the 4th in OT), or on the second in the last two minutes, whichever comes first.
- Team fouls include personal fouls by defensive players and any loose ball fouls (i.e. offensive fouls and technical fouls are not team fouls).
|
| WNBA |
| NCAA Men | - "Bonus" (1 free throw, plus another free throw if the first is successful) is awarded on the 7th, 8th and 9th foul of each half; the penalty is increased to two shots (often called "double bonus") on the 10th and subsequent fouls; overtime is an extension of the second half.
- Team fouls include all personal fouls, all contact and unsporting technical fouls, and all technical fouls to anyone on the bench.
- Note: No free throws awarded on an offensive foul (this is now in line with all other rules listed here; prior to the 2002-03 season, this rule only applied to the player in control of the ball).
|
| NCAA Women |
| CIS Men 2006 | Same as NCAA |
| CIS Women 2006 | - Penalty (2 shots) is awarded on any team foul on the 8th foul of each half unless the foul is an offensive foul; for overtime, second half foul count continues.
- Team fouls include all personal fouls, all contact and unsporting technical fouls, and all technical fouls to anyone on the bench.
|
Technical Foul — Penalty
| FIBA | 2 free throws and possession of the ball at centre; no possession at centre if the foul occurs before the first half (game would still start with a jump ball). |
| NBA | 1 free throw per technical foul; play resumes at the point of interruption; foul is charged to individual in question (and automatic fine assessed) |
| WNBA |
| NCAA Men | 2 free throws, play resumes at point of interruption. |
| NCAA Women | 2 free throws, play resumes at point of interruption. Technical fouls for excess time outs shall be penalised by two free throws, plus loss of possession of the ball. |
| CIS Men 2006 | 2 free throws, play resumes at point of interruption. |
| CIS Women 2006 |
Goaltending/Basket Interference
All rules disallow players from touching the ball on its downward flight toward the basket if it still has a chance to go in. Reaching through the basket to play the ball is also a violation. The major differences centre around what happens when a shot hits the rim and may or may not go in.
| FIBA | |
| NBA | - An imaginary cylinder exists that has the basket as its base. Touching the ball while any part of it is in this cylinder (and still has a chance to go in) is a violation.

| WNBA |
| NCAA Men |

| CIS Men 2006 | - An imaginary cylinder exists that has the basket as its base. Touching the ball while any part of it is in this cylinder (and still has a chance to go in) is a violation.
|
| CIS Women 2006 |
Zone Defence
| FIBA | Legal |
| NBA | Legal, however a defensive player may not stay in the lane (a.k.a. key, restricted area) for longer than three seconds if he is not actively guarding an opponent (penalty: technical foul, shot clock reset to 14 if necessary) |
| WNBA | Legal |
| NCAA Men |
| NCAA Women |
| CIS Men 2006 | Legal |
| CIS Women 2006 |
Free Throw Activity
Note: In all rules, the shooter of the free throw must wait for the ball to strike the rim before they can touch or cross the line.
| FIBA | - Maximum 5 players on the lane (3 opponents of shooter, 2 teammates)
- All spots designated (i.e. if left vacant, may not be filled by opponent)
- Players on lane leave on release of throw, others must stand behind free throw line extended & 3 point line and wait for ball to strike rim
- A shooter violation overrides all other violations. Similarly, if the free throw is good and the shooter did not violate, all other violations are ignored and the throw counts (one of my favourite FIBA rules).
- Five seconds to attempt the free throw (not strictly enforced)
|
| NBA | - Bottom four spaces must be occupied - a delay of game warning can be issued if they are not
- Maximum 5 players on the lane (3 opponents of shooter, 2 teammates)
- Players occupying lane spaces are prohibited from extending any part of their bodies into the space in front of an opponent until the free throw is released
- Players on lane leave on release of throw, others must stand behind free throw line extended & 3 point line (this distance is a change for the WNBA in 2008) but may also leave on release of throw
- A violation by any member of the shooting team can cancel an otherwise valid free throw
- Ten seconds to attempt the free throw
|
| WNBA |
| NCAA Men | - Maximum 6 players on the lane (4 opponents of shooter, 2 teammates)
- Bottom two spots must be occupied by opponents of the shooter; right to spots alternate along the lane; 3rd spots on the lane (normally occupied by opponents of the shooter) may be filled by a teammate of the shooter if the non-shooting team chooses not to fill it.
- Spots closest to the shooter (4th lane spots) may not be filled.
- Players on lane leave on release of throw, others must stand behind free throw line extended & 3 point line and wait for ball to strike rim
- A violation by any member of the shooting team can cancel an otherwise valid free throw
- Ten seconds to attempt the free throw
|
| NCAA Women | - Maximum 6 players on the lane (4 opponents of shooter, 2 teammates)
- All spots designated (i.e. if left vacant, may not be filled by opponent)
- Spots closest to the basket (below "the block") are not used (players fill the second, third and fourth spots from the basket).
- Players on lane leave on release of throw, others must stand behind free throw line extended & 3 point line and wait for ball to strike rim
- A violation by any member of the shooting team can cancel an otherwise valid free throw
- Ten seconds to attempt the free throw

| CIS Men 2006 | same as NCAA Men |
| CIS Women 2006 |
Minor Differences
- Player Numbers
- FIBA: Only the numbers 4-15 may be used in international competition (in exhibition or domestic play, any one- or two-digit number is acceptable)
NCAA: 00, 0, 1-5, 10-15, 20-25, 30-35, 40-45, 50-55; not both 0 and 00 on the same team;
NBA, WNBA: any one or two digit number; not both 0 and 00 on the same team. - Ball Over Backboard
- FIBA: The ball is still in play if it passes over the backboard in either direction, providing that it does not hit a basket support
NBA, WNBA, NCAA: Ball is out of bounds if it passes over the backboard in either direction (NBA/WBNA wording is "passes behind the backboard") - Travelling
- NBA/WNBA rule is a little more liberal than the current NCAA and FIBA rules when a player is coming to a stop. The NBA/WNBA rule is identical to the pre-1994 FIBA rule; in essence, once you have come to a legal stop, you always have a foot to pivot with. NCAA and current FIBA rules can leave a player without a pivot foot. As well, if you land with a staggered stop (i.e. one foot, then the other, with one foot clearly in front of the other), the back foot is the pivot foot in NBA/WNBA. In NCAA/FIBA, the first foot to touch is the pivot.
- Injured Player
- FIBA, NCAA: Referee stops play at an appropriate time to deal with injury (slightly different times in FIBA and NCAA). If an injured player is entitled to free throws and must leave the game, the substitute shall attempt the throws.
NBA, WNBA: Team must call 20 second or full timeout to stop for injured player. If an injured player is entitled to free throws and must leave the game, the opposing coach selects the player to take the throws. - Closely Guarded Player / 5 Second Violation
- FIBA: Player holding the ball for 5 seconds, actively guarded within one metre, anywhere on the court
NCAA: front court only, holding or dribbling the ball (not a combination of both) for 5 seconds, within 6'/2 m (Women: 3')
CIS Men 2006: Player holding the ball for 5 seconds, actively guarded within one metre, front court only.
NBA: No closely guarded rule; Illegal to dribble with your back to the basket for 5 consecutive seconds while you are between the baseline and the free throw line extended.
WNBA: No rule - Backcourt Violation("Over and Back") / Front Court & Back Court Status
- FIBA: Once you touch the front court, you have front court status (same applies to the back court). It is possible for a player (but not the ball) to have dual status as you progress from the back court to front court, so once you touch the front court as a ball carrier/dribbler, you must continue to proceed to the front court. Also, team control exists on a throw-in, so if the ball is thrown in from the front court to a player with back court status, it would be a backcourt violation.
NCAA: All three points (player's feet and the ball) must be in the front court, otherwise the ball retains/gains back court status. On a throw-in, a player may legally throw the ball directly to a teammate in the backcourt.
NBA, WNBA: Same concept of front and back court status as NCAA (i.e. three points). Same throw-in principle as FIBA (i.e. can't throw-in from front court to back). New in 2008: Exception made for frontcourt and midcourt throw-ins in the last minute of the game (4th period or any overtime) — may throw directly to backcourt. - 8 (or 10) Second Violation
- Once a team gains control of the ball in the backcourt, it has either 8 or 10 seconds (as specified below) to proceed to the frontcourt (i.e. the ball gains frontcourt status).
FIBA: 8 seconds. Count is not reset if ball is deflected out of bounds by defence or if possession is retained because of an alternating possession throw-in. Time out that advances the ball to mid-court in the last two minutes ends the count.
NBA, WNBA: 8 seconds. Count is reset if the defence kicks or punches the ball, is assessed a technical foul, or is issued a delay of game warning; or if play is stopped due to a player bleeding. For purposes of this rule, the ball gains front court status on a pass when it crosses the plane of the centre line.
NCAA Men: 10 seconds. Count ends (without penalty) if the ball becomes dead (e.g., if the defensive team deflects the ball out of bounds).
NCAA Women: No time limit (other than the shot clock). - Number of On-court Officials
- FIBA: A three-official system will be used for World and Olympic Championships, and may be used for other championships; mechanics similar to NCAA.
NBA, WNBA: A three-official system is used (different mechanics than NCAA/FIBA).
NCAA: Either two or three officials. - Three Point Try Status Change
- FIBA: Once a three point try has been released, if the ball is touched by any player in the two-point zone, the status of the try changes to a two-point try. (Note: Should a shooter be fouled in the act of shooting a three-point goal, and the try is unsuccessful, three free throws will be awarded; the status of the try does not change the status of the shooter.)
NBA, WNBA, NCAA: No rule.
- Rebounding Own Shot
- NBA, WNBA: Violation to be the first to touch ones own shot if it doesn't hit the rim or backboard (i.e. an "air ball").
All others: Legal (referee must judge that it was a try for goal, as poorly executed as it was ;-) - Ball Size
- As of September 2004, all Women's rules (FIBA, WNBA, NCAA, CIS) use the so-called Size 6 ball (previously, FIBA had used the same ball size for men and women). All Men's rules continue to use the larger ball.
- Instant Replay
- NBA, WNBA: Triggered automatically (no discretion); used to determine good field goals at the end of period as well as time remaining in period when the foul occurs with 0:00 on the clock; Also triggered automatically in 2008: used to determine severity of foul in Flagrant 2 (ejection) instance and any other factors that may have caused same; used to assist with identifying and penalizing players in an altercation.
NCAA: When available, shall be used to determine good field goals at the end of period as well as time remaining in period when the foul occurs with 0:00 on the clock (same as NBA); shall be used to determine who left the bench during a fight (and if a fight occurred); may be used (discretion of officials) in specific ways related to Free Throws (e.g., shooter, number of throws), Scoring (2 or 3 point goal, scorer errors), Timing (clock malfunction, game clock or shot clock operational errors — specific limits apply), or (new in 2007–08) to determine if a flagrant foul occurred in a Men's game.
FIBA: No rule. - Throw-in — Administration
- CIS Women 2006: If a violation occurs resulting in a throw-in from a team's back court, the official shall not handle the ball on such throw-in. The throw-in shall take place from within 1 m of the designated spot (if it is not, the official blows the play down and handles the throw-in from the designated spot). This is similar to the pre-1990 FIBA Rule.
Others: No rule — all such throw-ins are handled by an official.
Itsy Bitsy Niggly Ones
Yes, there are more! But I think that's quite enough for most of you.
