CM Punk has lost both of his UFC matches to date, but he is apparently not completely ruling out a return to mixed martial arts.
"The door is open," he said of a possible return Monday on Ariel Helwani's MMA Show (via Chamatkar Sandhu of ESPN). "I'm taking opportunities as they come. If there's a deadline it's coming up at the end of the year."
Punk most recently lost to Mike Jackson by unanimous decision at UFC 225 in June.
