British actor and former footballer Vinnie Jones has gone on trial in the USA on assault charges.
Jones was arrested and charged after being involved in a bar brawl last December.
Prosecutors at the trial in Sioux Falls, South Dakota, accuse Jones of punching Juan Trevino-Barrera in the head three times.
The 'X-Men star' and former Wimbledon player, who claims he acted in self defence, received hospital treatment after the incident for cuts to the face.
He was hit with a beer glass during the altercation.
The incident allegedly began when Trevino-Barrera asked Jones if "he was the guy from X-Men" to which he took offence.
Jones is charged with simple assault which carries a maximum punishment of one year in jail and a $1,000 (657) fine.
