Former WWE star CM Punk will not make his MMA debut at UFC 199 or 200 as previously expected, opting to undergo surgery for a herniated disc on Wednesday, according to MMAFighting.com.
Punk, 37, says that he has been dealing with the injury since his days as a wrestler and it got to the point where it had to be addressed recently.
“It got bad enough to the point where I couldn't do anything the week before I went to train with the New Jersey Devils last month,” he said. “One day I could manage, the next day I couldn't. I've been in agony for almost a month. Chiropractor, acupuncture, massage, cryotherapy ... nothing worked.”
Punk is scheduled to make his debut against Mickey Gall (2–0), who recently defeated Mike Jackson by a first-round rear-naked choke.
Punk signed with the UFC in December 2014. He began his wrestling career in 1999, becoming the WWE World Heavyweight Champion in 2008.
