A remarkable NFL return is set for Sunday.

Broncos linebacker Alex Singleton returned for the team’s “Sunday Night Football” clash on the road against the Commanders in Week 13 — just three weeks after he underwent emergency surgery for his sudden testicular cancer diagnosis.

“See you Sunday night!” the 31-year-oldcaptioned a photo of himself running out of the tunnel at Mile High.

Singleton shocked the league earlier this month when he announced a random NFL drug test helped detect signs of the cancer, and he was in surgery only a matter of hours after playing in the Broncos’ 10-7 “Thursday Night Football” win over the Raiders in Week 10.

Elevated levels of the hormone hCG [human chorionic gonadotropin] were detected, which caused an alarm because “this was not from anything external,” since Singleton said he was “diligent” about what he put into his body. 

He decided to share his story with the hope it would raise awareness and encourage others to seek out regular screening.

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

The seven-year linebacker only missed one game since — Denver’s massive 22-19 win over the Chiefs last week  — and is now game-ready just 23 days later.

ESPN reported Wednesday that was “tracking” to play Sunday evening.

Singleton had nine tackles in the Raiders game, which contributed to his team-best total of 89 across 10 games in his fourth season with the Broncos.

The California native was hoping to be back sooner rather than later, and with his quick turnaround, he will still have a major impact on the Broncos’ surging season as they lead the AFC West.
