When may an NBA jump-ball participant catch the ball, and how many taps are allowed?
A jumper cannot catch the tossed or tapped ball until it touches one of the eight nonjumpers, the floor, the basket, or the backboard. A tap by the other jumper alone does not lift that restriction, and each jumper may tap no more than twice. This guide follows NBA Official online rules checked October 15, 2026; the pages do not identify a season-specific edition.
For NBA readers trying to understand the stated playing-rule sequence, with all material facts stipulated. · Updated
The other jumper’s tap alone does not permit a catch
The catch restriction continues until one of four listed contacts occurs: a nonjumper, the floor, the basket, or the backboard. The list says one of the eight nonjumpers. Two jumpers trading taps does not satisfy it.
A jumper who catches before a listed contact commits an individual jump-ball violation. The stated remedy is an inbound for the opponent near the violation.
Count taps by each jumper
Each jumper may tap the ball at most twice on the jump. A jumper also cannot tap the toss before it reaches its highest point. If the toss falls to the floor without a jumper touching it, the official whistles it dead and signals another toss.
Nonjumpers have their own restrictions
The eight nonjumpers stay outside the restraining circle until the ball has been tapped. Teammates cannot take adjacent positions when an opponent wants one, and no player may stand immediately behind an opponent on the circle. The order of position choice follows which basket is nearer.
The toss makes the ball live, while a legal tap makes it alive. A jump-ball violation before a legal tap does not start either the game clock or the shot clock.
An untouched or bad toss is different from a player violation
An untouched toss that reaches the floor is thrown again. A bad toss or a violation by both teams also produces a repeat toss with the same jumpers. The source does not supply the missing departure-timing words in its separate rule clause, so this guide does not describe when a jumper may leave a half of the circle or any participant-selection policy.
Follow the contacts, not just the taps
Hypothetical: correctly designated Team Alder and Team Birch jumpers start in lawful positions. Alder taps once, Birch taps once, and Alder tries to catch the ball before it touches a nonjumper, the floor, the basket, or the backboard. Birch’s tap alone does not make the catch legal, so the individual violation gives the opponent an inbound. In a separate toss, Alder legally taps the ball before it touches the floor; Alder collects it after that floor contact, when the catch restriction has been lifted. In another sequence, Alder has already tapped twice on the jump and then taps again; that third tap exceeds the individual limit. Finally, an untouched toss reaches the floor and is repeated; separately, a stipulated bad toss is repeated with the same jumpers.
Related questions
Does the second jumper’s tap let the first jumper catch the ball?
No. The catch restriction ends only after the ball touches a nonjumper, the floor, the basket, or the backboard.
Does an untouched toss that hits the floor count as a jumper’s violation?
The official whistles the ball dead and signals another toss; that is separate from an individual jumper violation.
