Mike Tyson channeled his inner Hulk Hogan on Wednesday night -- ripping off his shirt and beating the hell out of a pro wrestler ... and it was awesome!!
It all went down on AEW's Dynamite -- where Chris Jericho and his allies in the Inner Circle were getting attacked by the guys in The Pinnacle, led by pro wrestling star MJF.
All of the sudden, Mike Tyson appeared -- and unleashed the fury all over Shawn Spears ... throwing punches in bunches and even launching a ground and pound attack!
