shot clock

A timer designed to increase the pace (and, consequently, the frequency of scoring) by requiring a shot to be released before the timer expires; if the ball does not touch the rim or enter the basket, a shot-clock violation is called, which results in a loss of possession for the shooting team. The time limit is 24 seconds in the NBA, WNBA, and FIBA play. 30 seconds in both men's and women's NCAA play, and 35 seconds in states that use a shot clock for NFHS play. See also air ball.
