Former CFL star, Denver Bronco LB Alex Singleton has surgery for testicular cancer

By Canadian Press on November 10, 2025.

CALGARY — Former CFL star and current Denver Broncos linebacker Alex Singleton has undergone surgery for testicular cancer and says he expects to return to the football field this season.

Singleton played three seasons for the Calgary Stampeders. He won a Grey Cup in 2018 and earned the CFL’s most outstanding defensive player award in 2017 before heading to the NFL.

The 31-year-old said in a social media post that he had surgery Friday after playing the previous night in Denver’s 10-7 win over the Las Vegas Raiders.

Singleton wrote that an elevated hormone showing up in his random drug test as part NFL’s drug testing prompted him to consult a urologist, who confirmed signs of testicular cancer.

The Californian believes the cancer was detected and treated early enough that he will play again this season.

Singleton spent his first three NFL seasons with the Philadelphia Eagles and is in his third with the Broncos.
