When does a jump-ball restriction end?

A jump-ball restriction ends when the tapped ball touches the floor, a nonjumper, the basket, or the backboard. This is important because it indicates the moment when the competitive aspect of the jump ball is over, and possession is established for the respective teams.

The act of tapping the ball begins the play, but until it contacts one of the specified items—floor, another player who was not involved in the jump, the rim, or the backboard—the jump-ball restriction is still in effect. The essence of this rule is to ensure that the initial jump ball situation is clear and controlled, allowing play to transition smoothly after the jump.

In this context, the other options do not accurately represent when the jump-ball restriction concludes. A whistle by the referee signals various events in the game but does not specifically relate to the jump-ball scenario. A player calling for a timeout does not impact the jump-ball restrictions, as these rules pertain to the initial possession. Lastly, there is no specified time limit that would conclude a jump-ball situation since it is solely based on the ball’s initial contact after the jump.
