A report from MMAFighting.com reveals that CM Punk has notified UFC that he has retired from mixed martial arts.

Punk was required to inform UFC of his status so he could be removed from UFC’s anti-doping program. In 2020 he was tested around 6 times.

Punk fought twice in MMA, both times for UFC. He lost his debut via first-round rear-naked choke submission to Mickey Gall at UFC 203 in September 2016. He subsequently fought Mike Jackson at UFC 225 in June 2018, losing a unanimous decision.

The Jackson fight was however later overturned to a "No Contest" ruling after Jackson tested positive for marijuana.
