Broncos' Alex Singleton Had Surgery for Testicular Cancer After Playing vs. Raiders

Denver Broncos linebacker Alex Singleton announced Monday he underwent surgery for testicular cancer.

"Thankfully, we believe the cancer was caught early with a great prognosis for me and my family," he said. "While we are still awaiting some additional test results, I fully expect to return to the field in the coming weeks."

Singleton said he had the procedure last Friday, a day after Denver's 10-7 win over the Las Vegas Raiders.

The Denver Broncos said a random drug screening by the NFL prompted Singleton to have further testing that uncovered the cancer.

"Our No. 1 priority is Alex's health and well-being, and we are grateful it appears the cancer was caught early," the organization said.

Singleton was on the field for every defensive snap against the Raiders, something that has been true in nine of his 10 starts in 2025. He had nine total tackles in the victory.

Broncos players voted the 31-year-old as one of their captains for this season, an honor he also received in 2024. His 89 combined tackles are the most on Denver's defense. He has been a tone-setter on a unit that's allowing the third-fewest yards and points per game.

Singleton said he publicized his diagnosis in order to serve as an example for others.

"Early detection and regular screenings save lives and can save loved ones from a lot of grief," he said.
