A jump ball situation occurs when:

A held ball is called.

The ball goes out-of-bounds and the officials are in doubt or disagree about

which of the opponents last touched the ball.

A double free-throw violation occurs during an unsuccessful last or only free

throw.

A live ball lodges on the basket support (except between free throws).

The ball becomes dead when neither team had control of the ball nor was

entitled to the ball.

After the cancellation of equal penalties against both teams, there are no other

foul penalties remaining for administration and neither team had control of the

ball nor was entitled to the ball before the first foul or violation.

All periods other than the first period are to begin.

12.4.4 Alternating possession Alternating possession is a method of causing the ball to become live with a throw-in rather than a jump ball. In all jump ball situations teams will alternate possession of the ball for a throw-in at the place nearest to where the jump ball situation occurs. The team that does not gain control of the live ball on the playing court after the jump ball which began the first period will start the alternating possession. The team entitled to the next alternating possession at the end of any period shall

start the next period with a throw-in at the centre line extended, opposite the scorer’s table.

12.4.5 Alternating possession:

Begins when the ball is at the disposal of the player taking the throw-in.

Ends when:

The ball touches or is legally touched by a player on the playing court.

The team taking the throw-in commits a violation.

A live ball lodges on the basket support during a throw-in.

12.4.6 The team entitled to the alternating possession throw-in shall be indicated by the

alternating possession arrow in the direction of the opponents’ basket. The direction of the alternating possession arrow is reversed immediately when the alternating possession throw-in ends.

A violation by a team during its alternating possession throw-in causes that team to

lose the alternating possession throw-in. The alternating possession arrow will be

reversed immediately, indicating that the opponents of the violating team will be

entitled to the alternating possession throw-in at the next jump ball situation. The 12.4.7
