A Jump Ball begins each contest and is used in many situations where possession cannot be determined. The following are the FIBA rules for both Jump Ball Procedures and Situations.
Jump Ball Procedure
12.2.1 Each jumper shall stand with both feet inside the half of the centre circle nearest to his team’s own basket with one foot close to the centre line.
12.2.2 Team-mates may not occupy adjacent positions around the circle if an opponent wishes to occupy one of those positions.
12.2.3 The official shall then toss the ball vertically upwards between the two (2) opponents, higher than either of them can reach by jumping.
12.2.4 The ball must be tapped with the hand(s) of at least one of the jumpers after it reaches its highest point.
12.2.5 Neither jumper shall leave his position until the ball has been legally tapped.
12.2.6 Neither jumper may catch the ball or tap it more than twice until it has touched one of the non-jumpers or the floor.
12.2.7 If the ball is not tapped by at least one of the jumpers, the jump ball shall be repeated.
12.2.8 No part of a non-jumper's body may be on or over the circle line (cylinder) before the ball has been tapped.
An infraction of Art. 12.2.1, 12.2.4, 12.2.5, 12.2.6, and 12.2.8 is a violation.
Jump Ball SItuations
Some leagues may use Alternating Possession instead of a Jump.
- 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 between the ring and the backboard (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.
