The maximum number of coach's challenges a team can have in a single game depends on the sport:
- NBA : Each team is entitled to one coach's challenge per game initially. If the first challenge is successful, the team is awarded a second challenge, making the maximum two challenges per team per game
- NFL : Each team starts with two challenges and can earn a third if they win both initial challenges. Thus, a team can have up to three challenges in a game, provided they are successful and have timeouts remaining to initiate challenges
- NHL : There is no fixed limit on the number of coach's challenges a team can make in a game, as long as each challenge is successful. However, an unsuccessful challenge results in a penalty, discouraging frivolous challenges
In summary:
Sport| Maximum Coach's Challenges Per Team Per Game
---|---
NBA| 2 (initial 1 + 1 if first is successful)
NFL| 3 (start with 2, earn 3rd if first two successful)
NHL| Unlimited (as long as each challenge is successful)
This reflects the current official rules and common practice in these major sports leagues.
