The Coach’s Challenge allows a head coach to trigger one instant replay review per game of a (1) called foul, (2) called out-of-bounds violation or (3) called goaltending or basket interference violation. Each team is entitled to one challenge in the game (regardless of whether the challenge is successful). As with other replay reviews, in order to overturn the event as called on the floor, there must be clear and conclusive visual evidence that the call was incorrect.
Below are Coach’s Challenge reviews by day and the season totals after each day’s games.
