Report: Manziel had fistfight with fellow wedding guest at Hawaiian resort

Less than a week after Johnny Manziel suggested he'd started to turn his life around, the troubled quarterback was allegedly involved in a fistfight with a man at a friend's wedding in Hawaii on Friday night, sources told TMZ Sports.

Things reportedly got heated between the former Cleveland Browns passer and a fellow wedding guest at the rehearsal dinner, with Manziel striking the man in the face at one point in the altercation.

The fight was believed to be over almost immediately. The police were not called to the scene, notes TMZ, and sources said Manziel insisted he was not the instigator and that he felt hounded by the man.

Manziel allegedly apologized to the man the next day in the form of a bottle of champagne sent to his room, with a note that read: "Truly apologize. Should have never done that. Know this won't make it better, but hope it starts the day off all right."

Manziel did not respond to TMZ's request for comment.
