Alex Singleton’s autumn took a serious and sobering turn quickly. The Broncos inside linebacker and team captain announced that he underwent surgery on Friday after being diagnosed last week with testicular cancer.
“Thankfully, we believe the cancer was caught early with a great prognosis for me and my family,” Singleton wrote on social media Monday. “While we are still awaiting some additional test results, I fully expect to return to the field in the coming weeks.”
Singleton revealed that he was selected for the NFL’s random drug testing program a little more than two weeks ago and was notified that he had elevated levels of the hormone hCG.
“Without a doubt, I knew with how diligent I am with what goes into my body that this was not from anything external that I may have taken. After speaking with my agent and wife, we decided to book an appointment with a urologist,” he explained.
He then visited Dr. Andrew Zilavy, who identified signs of a testicular tumor. A subsequent ultrasound confirmed the diagnosis.
Despite the diagnosis, Singleton played in Denver’s Thursday night win over the Raiders, participating in every snap as usual. The following day, he underwent surgery to remove the tumor.
“I wrestled with sharing such personal information publicly, but the fact is, if it helps one person decide to pay closer attention to their body, then it is well worth it,” Singleton wrote.
This story will be updated as more information becomes available.
