RULE NO. 14 – Coaches Challenge

To initiate a Challenge, the challenging team must take the following steps in sequence:

  1. The challenging team must call a legal timeout immediately after the call in question (unless a mandatory timeout or timeout called by the opposing team is already underway);
  2. The challenging team’s head coach must simultaneously signal for a Challenge by utilizing the instant replay signal (i.e., twirling an index finger) toward the game official(s) during the same interaction with the game official(s) in which the timeout was called or, if the timeout was called by a player on the challenging team, the challenging team’s head coach must simultaneously signal for the Challenge by utilizing the instant replay signal toward the game officials as the game official is notifying the scorekeeper of the timeout; and
  3. During the same interaction with the game official(s) in which the challenging team’s head coach signaled for the Challenge, the challenging team’s head coach must notify the game official(s) of the specific event that the team is challenging.

For purposes of this rule only, “immediately” shall mean that a timeout is called prior to the ball being given to the thrower-in, the ball being given to the free throw shooter, or the ball being tossed on a jump ball, whichever is applicable unless a mandatory timeout or timeout called by the opposing team is already underway).

b. To initiate a Challenge of an event that immediately preceded a mandatory timeout or timeout called by the opposing team, no later than 30 seconds from the start of the timeout (as measured by the timeout clock), the challenging team’s head coach must take the following steps in sequence:

  1. Signal for a Challenge by utilizing the instant replay signal toward the game officials; and
  2. During the same interaction with the game official(s) in which the challenging team’s head coach signaled for the Challenge, the challenging team’s head coach must notify the game official(s) of the specific event that the team is challenging.

c. In the event the game officials conference to determine the call on the floor (and, as a result, the final ruling on the play is unknown for a period of time), the window of time within which a team must immediately challenge the call starts after the officials notify the negatively affected team of the final ruling on the play. The negatively affected team’s window to challenge the final ruling on the play ends when the ball is given to the inbounder or free throw shooter, jump-ball is tossed, or 30 seconds after the team has been notified of the final ruling on the play in the event that a mandatory timeout or timeout by the opposing team has been called (whichever is applicable).

d. A team loses its opportunity to challenge the prior call if it is called for a delay-of-game after the call in question but prior to calling timeout and simultaneously signaling for a challenge.

e. Once instant replay is triggered by a valid Challenge, the official will notify the official scorer of the Challenge. The official scorer shall immediately record the Challenge and, once the instant replay review process is complete, the outcome of the Challenge (including whether the Challenge resulted in a loss of one timeout for the challenging time).
