CM Punk was involved in an altercation with one fan who got a little over-zealous during the Cage Fury Fighting Championships on Saturday night.
CM Punk was working as a commentator at the event, which took place at the Hard Rock Hotel in Las Vegas, Nevada.
Following the conclusion of the quick Christopher Daukaus us vs Danny Holmes fight, Punk could be heard telling someone to back off, before dropping his headset and apparently getting into it with the fan, who was ultimately removed from the event.
