NBA Likely To Introduce Coach’s Challenge For 2019/20

The NBA will implement a coach’s challenge during Summer League play in July and anticipates introducing the rule for the 2019/20 regular season, according to a league memo obtained by ESPN’s Zach Lowe.

Here’s how the new rule is expected to work, according to Lowe:

  • Coaches will get one challenge per game, whether or not it’s successful.
  • Called fouls, goaltending, basket interference, and out-of-bounds plays are the only calls that can be challenged. Uncalled fouls can’t be challenged.
  • Coaches must have a timeout available to use a challenge, and must use that timeout immediately after the call they want to challenge.
  • If the challenge is successful, the team will get its timeout back. If not, it will be lost.
  • The crew chief for that game’s referee crew will make the final call on challenges involving fouls. All other challenges will be decided by the NBA’s Replay Center.

As Lowe explains, the NBA has tested the challenge system in the G League over the last two years. The league plans to introduce it on a trial basis for the 2019/20 season “as part of a one-year pilot program,” per Lowe.

However, before it can become official, the NBA’s Board of Governors will need to approve it. According to Lowe, that vote is expected to take place on July 9, and would require support from at least two-thirds of the league’s teams. The NBA expects the rule to be passed, Lowe notes.
