Article 12

Jump ball and alternating possession

12-1Statement

The team that does not gain the first team control of a live ball after the opening jump ball at the start of the game shall be awarded the ball for a throw-in from the place nearest to where the next jump ball situation occurs, except from directly behind the backboard.

12-2Example

Two minutes before the start of the game, A1 is charged with a technical foul of any category.

Interpretation

One of the 5 team B starting players shall attempt the free throw with no line-up. As the game has not yet started, the direction of the alternating possession arrow cannot be placed in favour of any team yet. The game shall start with a jump ball.

12-3Example

The crew chief tosses the ball for the opening jump ball. Before the ball reaches its highest point, jumper A1 touches the ball.

Interpretation

This is a jump ball violation by A1. Team B shall be awarded a throwin from its frontcourt, close to the centre line. Team B shall have 14 seconds on the shot clock. As soon as the ball is placed at the disposal of the team B thrower-in, team A shall be entitled to the first alternating possession throw-in.

12-4Example

The crew chief tosses the ball for the opening jump ball. Before the ball reaches its highest point, non-jumper A2 enters the centre circle from the

  • (a) backcourt.
  • (b) frontcourt.
Interpretation

In both cases, this is a jump ball violation by A2. Team B shall be awarded a throw-in close to the centre line, if from its

  • (a) frontcourt, with 14 seconds on the shot clock.
  • (b) backcourt, with 24 seconds on the shot clock. As soon as the ball is placed at the disposal of the team B thrower-in, team A shall be entitled to the first alternating possession throw-in.
12-5Example

The crew chief tosses the ball for the opening jump ball. Immediately after the ball is legally tapped by jumper A1

  • (a) a held ball between A2 and B2 occurs.
  • (b) a double foul between A2 and B2 occurs.
Interpretation

In both cases, as the control of a live ball was not yet established, the referee cannot use the alternating possession procedure. The crew chief shall administer another jump ball in the centre circle and A2 and B2 shall jump. The time consumed on the game clock, after the ball was legally tapped and before the held ball/double foul occurred, shall remain valid.

12-6Example

The crew chief tosses the ball for the opening jump ball. Immediately after the ball is legally tapped by jumper A1, the ball

  • (a) goes directly out-of-bounds.
  • (b) is caught by A1 before it touches one of the non-jumpers or the court.
Interpretation

In both cases, team B shall be awarded a throw-in as the result of A1’s violation. If the throw-in is administered from its backcourt, team B shall have 24 seconds on the shot clock. If from its frontcourt, team B shall have 14 seconds on the shot clock. As soon as the ball is placed at the disposal of the team B thrower-in, team A shall be entitled to the first alternating possession throw-in.

12-7Example

The crew chief tosses the ball for the opening jump ball. Immediately after the ball is legally tapped by jumper A1, B1 is charged with a category 1 technical foul.

Interpretation

Any team A player shall attempt 1 free throw with no line-up. As soon as a team A player receives the ball for the free throw, the direction of the alternating possession arrow shall be placed in favour of team B. The game shall be resumed with a team B alternating possession throw-in from the place nearest to where the ball was located when a technical foul occurred. If the throw-in is administered from its backcourt, team B shall have 24 seconds on the shot clock. If from its frontcourt, team B shall have 14 seconds on the shot clock.

12-8Example

The crew chief tosses the ball for the opening jump ball. Immediately after the ball is legally tapped by jumper A1, A2 is charged with a flagrant foul committed against B2.

Interpretation

B2 shall attempt 2 free throws with no line-up. As soon as B2 receives the ball for the first free throw, the direction of the alternating possession arrow shall be placed in favour of team A. The game shall be resumed with a team B throw-in from the throw-in line in its frontcourt opposite the scorer’s table (as part of the flagrant foul penalty). Team B shall have 14 seconds on the shot clock.

12-9Example

Team B is entitled to a throw-in under the alternating possession procedure. A referee and/or a scorer makes an error and the throw-in is erroneously awarded to team A.

Interpretation

After the ball touches or is legally touched by a player on the court, the error cannot be corrected. As the result of the error, team B shall not lose its right to the next alternating possession throw-in at the next jump ball situation.

12-10Example

Simultaneously with the game clock signal sounding for the end of the first quarter, B1 is charged with

  • (a) a disruptive foul
  • (b) a flagrant foul against A1. The referees decide that the game clock signal sounded before B1’s foul occurred. Team A is entitled to the alternating possession throw-in to start the second quarter.
Interpretation
  • (a) A disruptive foul cannot occur during an interval of play. B1’s foul shall be disregarded and the second quarter shall start with a team A throw-in from the centre line extended. Team A shall have 24 seconds on the shot clock.
  • (b) The flagrant foul shall not be disregarded. Before the start of the second quarter, A1 shall attempt 2 free throws with no line-up. The game shall be resumed with a team A throw-in from the throw-in line in its frontcourt opposite the scorer’s table. Team A shall have 14 seconds on the shot clock. Team A shall not lose its right to the next alternating possession throw-in at the next jump ball situation.
12-11Example

Shortly after the game clock signal sounds for the end of the third quarter, B1 is charged with a category 1 technical foul. Team A is entitled to the alternating possession throw-in to start the fourth quarter.

Interpretation

Any team A player shall attempt 1 free throw with no line-up before the start of the fourth quarter. The fourth quarter shall start with a team A throw-in from the centre line extended. Team A shall have 24 seconds on the shot clock.

12-18Example

A1’s shot for a goal is in the air when the shot clock signal sounds, followed by the ball lodging between the ring and the backboard. The alternating possession arrow favours team A.

Interpretation

This is a jump ball situation. After the throw-in from behind the endline in its frontcourt, team A shall have 14 seconds on the shot clock.

12-19Example

B2 is charged with a disruptive or flagrant foul committed against A1. During the last free throw with no line-up

  • (a) the ball lodges between the ring and the backboard.
  • (b) A1 steps on the free-throw line while releasing the ball.
  • (c) the ball misses the ring.
Interpretation

In all cases, the free throw is unsuccessful. The game shall be resumed with a team A throw-in from the throw-in line in its frontcourt opposite the scorer’s table. Team A shall have 14 seconds on the shot clock.

12-20Example

After A1’s throw-in from the centre line extended to start a quarter, the ball lodges between the ring and the backboard in team A’s frontcourt.

The alternating possession arrow favours team A. During the interval of play after the first quarter, B1 is charged with a flagrant foul committed against A1. A1 shall attempt 2 free throws with no line-up, followed by a team A throw-in from the throw-in line in its frontcourt, opposite the scorer’s table, to start the second quarter. The alternating possession arrow in favour of team A remains unchanged. After the throw-in, the ball lodges between the ring and the backboard in team A’s frontcourt.

Interpretation

This is a jump ball situation. The game shall be resumed with a team A throw-in from behind the endline in its frontcourt, except from directly behind the backboard. Team A shall have 14 seconds on the shot clock. The direction of the alternating possession arrow shall be reversed immediately after the team A throwin has ended.

12-22Statement

A held ball occurs when one or more players from opposing teams have one or both hands firmly on the ball so that neither player can gain control of the ball without undue roughness.

12-23Example

A1 with the ball in the hands is in the act of shooting on a drive to the basket. At this time, B1 places the hands firmly on the ball and A1 now takes more steps than allowed by the traveling rule.

  • (a) thrower-in A1 steps on the court while having the ball in the hands.
  • (b) A2 moves the hands over the boundary line before the ball is thrown-in over the boundary line.
  • (c) thrower-in A1 takes more than 5 seconds to release the ball.
Interpretation

In all cases, this is a throw-in violation by A1 or A2. The game shall be resumed with a team B throw-in from the place of the original throw-in. The direction of the alternating possession arrow shall be reversed immediately in favour of team B.

12-26Statement
