Punk broke the news officially to Unfiltered hosts Matt Serra and comedian Jim Norton.
The former WWE star signed with the UFC in December 2014 to much buzz and most expected him to have fought by now, but a series of injuries sidelined him.
The Chicago native left WWE in early 2014 after butting heads with company execs.
He stunned the pro-wrestling and MMA worlds later that year by announcing his signing with the UFC.
Instead of giving into them, he turned away from them and decided to join the Straight Edge movement of being Alcohol, Drug and Cigarette free.
In his teen years, Brooks become a highly disciplined fighter in kick boxing and karate.
Punk, whose real name is Phil Brooks, said he was just cleared by doctors this week after a back injury put him on the shelf in February.He has been training for more than a year now at Roufusport in Milwaukee.As we previously noted, UFC is currently working on a documentary special profiling Mickey Gall, who is expected to be Punk’s first opponent, and the release of the special would coincide for an August 20th fight at UFC 202.If the fight does indeed take place at UFC 202, it will join a card headlined by Conor Mc Gregor vs Nate Diaz 2, but Botter was “careful” to note he hopes he didn’t ruin any announcements.The date for CM Punk's highly anticipated debut has been set.
