CM Punk – MMA (Hasn’t made his UFC debut yet)
CM Punk may be the longest reigning WWE Champion of the current era, having the held the belt for a whopping 434 days. He may be one of the best WWE wrestlers ever. But having signed a contract with UFC about 18 months ago, he is yet to make his professional debut. It may be hard to admit for a CM Punk fan, but it doesn’t look like it’s going to happen anytime soon. CM Punk was scheduled to face against another UFC newcomer, Mickey Gall at UFC 199. But he had to undergo emergency surgery on his back to restore a herniated disc. His debut was moved to UFC 200, but CM Punk, in an interview with the MMA Hour, said that he wants to make his UFC debut at Madison Square Garden at UFC 205 on November 12. But even chances of that look bleak as Punk has lost nearly all of his training bouts and a lot of MMA fighters believe that Phil Brooks (CM Punk) might not be able to compete in a UFC ring, given his history with injuries and recent performances.
