Broncos linebacker Alex Singleton announced via social media on Monday afternoon that he underwent successful surgery for testicular cancer last Friday.
Singleton shared the stunning news and diagnosis with teammates and coaches on Monday, but he expressed optimism about his outlook, calling himself a “lucky man.”
“Thankfully, we believe the cancer was caught early with a great prognosis for me and my family,” he said via social media. “While we are still awaiting some additional test results, I fully expect to return to the field in the coming weeks.
I shared this news with our team this morning.
I’m grateful for everyone’s support and can’t wait to get back on the field soon!

Singleton said that he first became aware something was amiss via the NFL’s drug-testing program, which informed him that he had an elevated level of hcG — human chorionic gonadotropin.
“Without a doubt, I knew with how diligent I am with what goes into my body that this was not from anything external I may have taken,” Singleton said in his statement posted on social media. “After speaking with my agent and wife, we decided to book an appointment with a urologist immediately to confirm the diagnosis.”
The appointment with Dr. Andrew Zilavy revealed signs of a testicular tumor. The diagnosis was confirmed last Monday, one day after the Broncos defeated the Houston Texans.
Remarkably, Singleton played well with the specter of the diagnosis and surgery looming over him, notching nine tackles in the Broncos’ 10-7 win over the Las Vegas Raiders on Thursday night.
Singleton decided to share his diagnosis, believing his platform could help others.
“I wrestled with sharing such personal information publicly. But the fact is, if it helps one person decide to pay close attention to their body, then it is well worth it,” Singleton said in his statement.
“Early detection and regular screenings save lives and can save loved ones from a lot of grief.”
