A third person has been arrested over an alleged assault after Norwich City's play-off semi-final match against Leeds United.
The victim, who is in his 60s, was reported to have been punched outside the ground on Carrow Road on Sunday.
Police said they believed an object had also been thrown, cutting the man's chin, and arrested two men at the scene, one of whom was later charged.
A man in his late teens was arrested on Monday night on suspicion of assault and a public order offence. He was bailed until 13 July.
