Simon Cowell does not take part in the finale of America’s Got Talent’s 21st season while he recovers from surgery, according to multiple reports. His absence means he does not join the judges for the performances and the results episode.

With Cowell unavailable, outlets report that KSI—a British YouTuber and influencer—will step in as a guest judge. He is scheduled to join the show’s regular panel members, including Howie Mandel, Sofia Vergara, and Mel B, during the finale segment that includes both the live performances and the results.

Both sources attribute the change to Cowell’s health and recovery process, noting that guest judges have been used at points when he has been away. The reports do not suggest changes to the show’s overall finale format beyond the temporary adjustment to the judging lineup.
