Simon Cowell is missing several America’s Got Talent live shows because he is undergoing a routine procedure related to his back. His representative said the absence should last only a few weeks and that Cowell is expected to return. He has not quit AGT, and NBC has not announced a permanent replacement.
The timing has worried viewers because Season 21 has entered its live phase, when Cowell normally helps judge the remaining acts alongside Howie Mandel, Sofía Vergara and Mel B. For now, the clearest answer is that this is a temporary medical break connected to his continuing back issues.

Why Is Simon Cowell Missing the AGT Live Shows?
Cowell is temporarily stepping away to have back surgery. A spokesperson described the procedure as routine and said he would be back in a few weeks. No report has suggested that his absence is connected to a dispute with NBC, a cast shake-up or a plan to leave the series.
That distinction is important. Cowell is not only a judge but also the creator and an executive producer of the show. His temporary absence changes the live judging panel, but it does not alter his long-term position within the Got Talent franchise.
Is the Surgery Related to Simon Cowell’s 2020 Bike Accident?
The new procedure is related to Cowell’s back, and his medical history provides important context. In August 2020, he fell from an electric bike at his Malibu home and broke his back in three places. He underwent a lengthy operation and later spoke about having metal rods and screws in his back.
Cowell also said the injury caused lasting nerve damage and required a difficult period of rehabilitation. He missed part of AGT Season 15 while recovering. In 2022, another electric-bike accident in London left him with a broken arm and added to concerns about his health.
However, viewers should not assume that the 2026 surgery means his condition has suddenly become critical. His representative specifically characterized it as routine and gave a short expected recovery window. No further diagnosis or emergency has been announced.
When Will Simon Cowell Return to AGT?
An exact return date has not been announced. The current expectation is that Cowell will miss a couple of weeks of filming and then return to the judging panel. Because recovery times can change, NBC and Cowell’s representatives remain the best sources for a confirmed episode date.
Until then, the competition will continue. Season 21 premiered in June 2026, and the live shows began in August. Terry Crews remains the host, with Howie Mandel, Sofía Vergara and Mel B continuing as judges.
Who Will Replace Simon Cowell on the Live Panel?
Guest judges are expected to fill Cowell’s seat during at least some of his absence, but NBC had not confirmed the names as of August 25, 2026. Any list circulating without an NBC announcement should be treated as speculation.
A guest judge can score performances and comment on acts, but the temporary arrangement does not make that person a permanent member of the panel. Cowell’s role is still waiting for him when he is medically cleared to return.
How Simon Cowell’s Absence Could Affect the Live Shows
Cowell often serves as the panel’s bluntest critic, particularly when an act has strong presentation but weak execution. His comments can frame how viewers discuss a performance, even though the public has a decisive role during the live rounds.
A rotating guest judge could change the chemistry from week to week. It may also give the show a chance to bring in former contestants, musicians, comedians or other television personalities who understand live performance. The key practical effect is a temporary change in perspective, not a change to the competition’s basic format.

Is Simon Cowell Leaving America’s Got Talent?
No. There is no evidence that Cowell is leaving America’s Got Talent. The announced reason for his absence is surgery, and his team has already said he plans to return. Headlines describing him as “missing” should not be read as confirmation of a resignation.
Cowell has remained one of the defining figures in modern television talent competitions. His presence links AGT to the wider Got Talent franchise and to earlier shows such as American Idol and The X Factor. A short recovery break does not change that role.

Cowell has not announced an exit, and viewers should expect him to return once his doctors clear him.
