CM Punk has no regrets over his lackluster run inside the Octagon.
Best known for his work in the world of pro wrestling, Punk — real name Phil Brooks — walked away from the sports entertainment industry in 2014 after becoming disenfranchised by the direction of his employer, World Wrestling Entertainment.
During his time away from the squared circle, Punk signed a deal with the UFC and made his promotional debut at UFC 203 against Mickey Gall. Punk was promptly pummeled and forced to tap out via a rear-naked choke less than halfway through the opening round.
