A ball can be used an infinite number of times in NBA games, as long as it maintains a strict set of criteria which is examined by league officials before each and every game.
Here is a general outline of the league’s handling of basketballs:
- All teams are sent 72 balls at the beginning of the season.
- Testing of game balls will take place in each arena prior to the start of the game.
- Equipment managers or ball boys take three basketballs to the officials’ locker room prior to the game.
- The officiating crew chief will inspect the three game balls for wear/tear and ensure that the balls comply with the NBA-approved ball pressure specification of between 7½ and 8½ PSI.
- The crew chief will bring all three game-ready balls to the court during the warm-up period.
- The crew chief then selects the game ball from the three available balls.
- If a problem exists with the ball used in the game, one of the two alternate balls will be used.
- All game officials have been provided with portable air gauges to carry with them to each of their assigned games
