CM Punk’s UFC run was memorable for all the wrong reasons.
In 2016, the Punk, whose real name is Phil Brooks, attempted to follow in the footsteps of Brock Lesnar, transitioning from the world of sports entertainment to mixed martial arts. Unfortunately, he failed to replicate the success of the former UFC heavyweight champion, getting absolutely manhandled by Mickey Gall in his Octagon debut at UFC 203.
Punk returned two years later only to lose a unanimous decision against Mike Jackson, though the result was ultimately overturned to a no-contest after Jackson tested positive for marijuana.
