Denver Broncos middle linebacker Alex Singleton revealed he had surgery to remove testicular cancer a day after playing against the Las Vegas Raiders.
Singleton announced the health scare on social media, saying the diagnosis came after a league-mandated drug test “a little over two weeks ago” showed he had elevated levels of the hormone hCG, prompting further discussions with doctors.
They discovered a tumor that needed to be surgically removed, and Singleton said he has a “good prognosis” for a full recovery.

“Fortunately, we believe the cancer was caught early with a good prognosis for me and my family,” he said in a statement. “While we are still awaiting some further test results, I fully expect to return to the track in the coming weeks.”
Singleton added that he saw Dr. Andrew Zilovy, a urologist, who determined that he showed signs of having a testicular tumor.

“I immediately contacted the Broncos and they put me in touch with Dr. Geoff Ledgerwood who was able to perform an ultrasound immediately to confirm the diagnosis,” Singleton’s statement continued. “And then on Friday, after playing in the Raiders game the night before, I had surgery to remove the cancerous tumor and begin the road to a full recovery.”
Singleton said he told his teammates about the situation Monday before revealing it publicly. He admitted he had second thoughts about telling the world, but felt his story needed to be shared.

“I struggled with sharing such personal information publicly,” he said. “But the fact is, if it helps one person decide to be more aware of their body, then it’s worth it. Early detection and regular screenings save lives and can save loved ones a lot of grief.”
Singleton has been one of the most consistent linebackers in recent seasons, ranking fifth in the league in tackles (89) through 10 games.
Before suffering a season-ending injury three games into his 2024 campaign, Singleton, a Broncos defensive captain, recorded 177 combined tackles in 2023 after posting 163 in 2022 during his first season in Denver.

Singleton’s career began in the Canadian Football League, where he gained recognition for his performances with the Calgary Stampeders between 2016 and 2018. Singleton, a Montana State University product, was noticed by the Philadelphia Eagles and played three seasons with the franchise before signing with the Broncos.
