What happened to Simon Cowell? AGT judge steps away temporarily; Kenan Thompson to fill in
What Happened to Simon Cowell? AGT Judge Gets Back Surgery
Bharatmorning.com – What happened to Simon Cowell this summer? The answer is straightforward: a scheduled spinal procedure that will keep the longtime talent-show executive away from the "America's Got Talent" judging panel for several weeks. His representatives have characterized the operation as entirely routine, though it adds another entry to a well-documented history of back injuries that stretches back to a dramatic cycling accident in 2020.
Season 21 Goes On Without Its Fourth Voice
In August 2026, the show's producers confirmed the judge would miss the live broadcasts of Season 21 while he heals. No fixed return date was announced, so the panel's composition will be handled episode by episode. The August 25 live show already aired as a trio — Howie Mandel, Sofia Vergara, and Mel B absorbed the full judging load, and the empty chair beside them served as a visible placeholder for the absent executive.
To bridge the gap for the third round of quarterfinals airing September 1, AGT announced via its official Instagram account on August 28 that Kenan Thompson would take the vacant seat. Thompson will complete the four-person lineup for that single broadcast, joining Mandel, Vergara, and Mel B.
The 2020 Crash That Set the Pattern
The current surgery is a far quieter event than the one that first put the judge in a hospital bed. In August 2020, while testing a newly purchased electric trail bike at his Malibu home, he lost control, was thrown roughly eight feet into the air, and landed on his back, fracturing part of his spine. He posted to Instagram within hours, pairing the news with a wry public-safety aside:
"Some good advice … If you buy an electric trail bike, read the manual before you ride it for the first time. I have broken part of my back. Thank you to everyone for your kind messages."
On The Kelly Clarkson Show in June 2021, he elaborated on the mechanics, noting that the particular e-bike carried far more torque than he had expected. He recalled the immediate aftermath with characteristic dark humor:
"I knew I'd broken my back in that second, and somehow managed to get back into my bedroom. I'm lying in my bed, and covered in blood, waiting for the ambulance."
Recovery, Setbacks, and Stubbornness
The repair operation ran close to five hours and included multiple spinal-fusion procedures plus a metal rod to stabilize the damaged vertebrae. Because the crash landed mid-season, he missed the remainder of AGT Season 15 live shows — his first extended absence from the franchise in years.
Healing proved neither quick nor linear. Months later, renewed pain surfaced while he played soccer with his son, signaling incomplete bone consolidation. Then, in February 2022, a separate e-bike fall in London broke his arm, compounding an already fragile rehabilitation timeline. Despite two major spinal and limb injuries within a two-year window, he showed no intention of giving up electric cycling. Speaking to Today in 2023, he was blunt:
"I'm still gonna stay on my bike. I'm obsessed with these things."
Kenan Thompson: The Trusted Stand-In
This is not the comedian's first stint as a fill-in. He previously occupied the chair in August 2020, immediately after the Malibu crash, joining Mandel, Vergara, and then-judge Heidi Klum for a single live episode. His return to the role underscores the show's reliance on a small circle of trusted entertainers to preserve continuity when a principal judge is unavailable.
Now 48, Thompson has been a cast member of Saturday Night Live since 2003, making him the longest-tenured performer in the sketch show's history. Decades of weekly cold opens, hosting duties, and live-audience improvisation position him as a natural fit for the high-pressure, real-time environment of a talent-competition panel.
