America’s Got Talent names guest judge to fill in for Simon Cowell

America’s Got Talent is making a temporary change to its judging panel as Simon Cowell steps away from the competition while recovering from a routine medical procedure.

The longtime judge will miss several weeks of the NBC talent competition after undergoing a back procedure. Cowell’s representative previously confirmed that the operation was routine and that the 66-year-old music mogul is expected to return to the show within a few weeks. (EW.com⁠)

Now, the show has revealed who will take Cowell’s seat.

Kenan Thompson has been announced as the guest judge for the third round of America’s Got Talent Season 21 quarterfinals, scheduled for Tuesday, September 1. The comedian and longtime Saturday Night Live star will join Howie Mandel, Sofía Vergara and Mel B as the remaining judges continue deciding which contestants deserve a place in the next stage of the competition.

Thompson is already familiar with the AGT judging table. He previously stepped in as a guest judge during Cowell’s absence following his serious 2020 electric-bike accident. His return therefore gives the show a familiar personality while Cowell takes time to recover. (NBC⁠)

Cowell’s current medical procedure is connected to his longstanding back problems. In 2020, he suffered a severe back injury after falling from an electric bike at his home in Malibu. The accident required major surgery and a lengthy recovery. He later faced another bike-related accident in 2022, adding to his history of back and physical issues. (Fox News⁠)

Despite his absence, the America’s Got Talent competition is continuing at an important point in Season 21. The quarterfinals are bringing some of the strongest acts back to the stage as contestants compete for a chance to reach the semifinals and ultimately the finals.

The September 1 episode will feature 11 acts competing for advancement, with one performer also receiving a Golden Buzzer that guarantees a place in the finals. (People.com⁠)

Cowell’s absence will undoubtedly be noticeable. His blunt opinions and famously tough judging style have become an important part of America’s Got Talent since he joined the panel. Still, the temporary change gives Thompson an opportunity to bring his own energy and humor to the competition.

For now, fans can expect Thompson to occupy Cowell’s chair while the music executive focuses on his recovery. With Cowell expected back in the coming weeks, his temporary departure appears to be just that—a short break rather than a permanent change to the AGT judging panel.
