As part of the ongoing enhancement of the Euroleague Basketball rulebook to ensure that games in the Turkish Airlines EuroLeague and BKT EuroCup are both fair to participants and clear to fans, Euroleague Basketball has added and modified several rules ahead of the 2023-24 season.
These include an additional coach's challenge for every game, new situations that referees can review during games, and a change in the disqualification rules for players or staff members on the bench during an on-court altercation.
Head coaches will now get two challenges to use during each game, but must use one of them in the game's first 38 minutes or lose it. In order to help speed up games, referees will now be able to initiate a foul review only in the final 2 minutes of a game or the final 2 minutes in overtime. Coaches may still use a challenge to initiate a foul review at any time.
Two new types of calls will now be open to review: one, whether or not a player was fouled in the act of shooting; and two, whether the shot clock requires resetting or not in situations when there is a review to determine if the ball touched the rim. In both cases, a coach may use a challenge for these calls. The referees may only initiate such reviews in the final 2 minutes of a game or the final 2 minutes in overtime.
Going forward, any player or team staff leaving the bench during an on-court altercation who does not become actively involved in the disturbance will not be disqualified. This assumes that the referees will be able to review footage and confirm that the bench player was not involved.
Finally, all jump ball situations will now see the ball put into play at the circle (either foul free-throw line or center court) that is nearest to the position where the previous action occurred.
