Kenan Thompson Steps In as Guest Judge on ‘America’s Got Talent’ While Simon Cowell Recovers From Back Surgery
Simon Cowell, the long-time sharp-tongued judge at the center of “America’s Got Talent,” is temporarily stepping away from the panel as he recovers from back surgery. The 66-year-old music executive and television personality will be replaced by actor and comedian Kenan Thompson for the show’s upcoming quarterfinals episode, giving fans one of the most recognizable celebrity guest judges the franchise has seen in recent memory.
Cowell’s representative confirmed that the procedure was routine and that he is expected to return to the judges’ table “in a few weeks.” The timing puts his absence right in the middle of the most competitive stretch of Season 21 of “America’s Got Talent”, as the show barrels toward its finale.
Why Kenan Thompson Is Taking Simon Cowell’s Seat
The show announced Thompson’s guest-starring role on Friday through its official social media channels, writing, “A comedy legend is taking over the Judges’ table.” Thompson will sit alongside returning judges Mel B, Howie Mandel, and Sofia Vergara, with Terry Crews continuing as host.
Thompson is best known as the longest-tenured cast member on “Saturday Night Live,” a run that has earned him multiple Emmy Awards and made him a household name in comedy. His crossover into reality competition judging brings a fresh, energetic perspective to a panel that has historically leaned on music industry veterans and professional entertainers.
The episode featuring Thompson airs on September 1 and covers the round 3 quarterfinals. Producers have hinted that additional guest judges could be announced for later episodes as Cowell’s recovery continues, though no further names have been confirmed.
A History of Guest Judges Filling In
This season has already leaned heavily on guest judges to keep the panel lively. Earlier episodes featured appearances from comedian Nikki Glaser, Spice Girl Emma Bunton (a fellow bandmate of Mel B), and singer-actress Lele Pons. The rotating guest-judge format has become a signature element of recent AGT cycles, giving producers flexibility and offering viewers a rotating mix of perspectives.
Simon Cowell’s Back Surgery and Past Health Scares
This isn’t Cowell’s first serious encounter with spinal issues. In 2020, he broke his back in a near-fatal electric bike accident near his home in Malibu, California. The injuries were severe enough that doctors initially feared he might never walk again.
“It could have been a lot worse. When I saw the X-ray, I really nearly smashed my spine to pieces, so I literally wouldn’t have been able to walk,” Cowell told “Extra” in a February 2021 interview.
He later recovered and returned to television, but the incident underscored how quickly a routine activity could result in serious injury. The current surgery, while described as routine by his representatives, is a reminder that Cowell has dealt with ongoing back issues since the 2020 crash. At 66, recovery timelines for spinal procedures can be unpredictable, and AGT producers appear to be planning for a multi-week absence rather than a quick return.
Cowell’s Legacy on AGT and Reality Television
Cowell has been a defining presence on “America’s Got Talent” since the show’s early years, currently in his 11th season as a judge. His reputation for blunt, no-nonsense critiques — and his golden buzzer moments that have launched careers — have made him one of the most influential figures in reality competition television.
Beyond AGT, Cowell previously judged nine seasons of “American Idol” and has served as a judge on international franchises including “The X Factor” and “Britain’s Got Talent.” He is widely credited with shaping the modern talent competition format, having mentored artists like One Direction, Kelly Clarkson, and Leona Lewis through earlier editions of his shows.
What’s Next for Season 21
Season 21 of “America’s Got Talent” premiered on June 2, and the finale is scheduled for September 23. With the competition now in its final stretch, the stakes are unusually high for the remaining contestants, and Cowell’s absence during the quarterfinals comes at a pivotal moment.
Thompson’s guest appearance is expected to inject humor and a different judging style into the panel. While Cowell is known for direct, often critical feedback rooted in music industry experience, Thompson’s comedy background could lean toward more lighthearted, celebratory responses — potentially reshaping the tone of the broadcasts while he is away.
For viewers wondering whether Cowell will make it back in time for the finale, his representatives have suggested he will likely return within weeks, and producers appear confident enough in his recovery timeline to continue with the season as planned.
Where the Show Stands Now
As of the latest episode announcements, the September 1 episode featuring Thompson will mark the first quarterfinals round. Additional guest judges may be announced for subsequent episodes, but no further official names have been released. The show’s format typically narrows the field through multiple elimination rounds before crowning a winner on finale night.
Whether Cowell returns for the finale itself remains the big question, but his representatives have described the surgery as routine, suggesting a return is likely before the September 23 finale.
