CM Punk is a pro wrestler who trains with Rener Gracie and is actively involved in MMA.

He’s friends with several fighters, but recently decided to walk away from the WWE.

Rumors of a move to MMA quickly started up, and one person decided to act on a possible fight.

Jason Frank, who played the Green Power Ranger on Mighty Morphin Power Rangers, a kids television show, challenged Punk to a fight. Frank is a seventh-degree black belt in karate and a purple belt in Brazilian jiu-jitsu.

Frank won four amateur fights and scored a victory via submission in 2010 in his pro debut. He was scheduled to compete for Legacy FC in 2011, but an injury kept him out.

“So now that CM Punk is out of his contracts and wants to do MMA. Why not me?” Frank wrote on Instagram. “He already said he fight me. I got this on video from a fan. Come on CM Punk we could make this a awesome fight.”
