Talk all the shit you want about Cathal, but he has fought 21 times (won 17) and had his first pro fight 6 years ago. CM Punk has zero amateur fights, zero professional fights, zero martial arts background (a little bit of karate training does not count) and he has been training MMA for only 7 months. Cathal would absolutely murder him and no athletic comission should allow this fight to happen. UFC should sign some non impressive dude with less than 5 pro fights. You say that Punk owned him on Twitter (which he didn't by the way), but Pendred would send him to a hospital. It would be Punk's first and last fight.
