AUGUSTA, Maine (AP)   A Maine mixed martial art fighter is losing his argument that he was defending himself when he repeatedly punched an unconscious victim in the head.

Maine’s Supreme Judicial Court upheld Richard Matthews’s conviction of aggravated assault for beating a man outside a bar in 2015. The judges say evidence doesn’t support his self-defense claim.

A bouncer testified then-45-year-old Matthews spun the victim around and punched him in the face until he fell to the ground. He says Matthews then sat on top of and repeatedly punched the injured victim.

Matthews says he thought the victim was going to grab his wife’s rear end. Matthews says he wanted to make sure the victim didn’t hurt him and stayed down. His attorney didn’t immediately respond to request for comment Tuesday.
