Former world boxing champion Eamonn Magee has been convicted of head-butting a man at a GAA social club in north Belfast last August.
Victim Kevin McLaughlin told Belfast Magistrates' Court he was attacked after asking Magee to leave the Ardoyne Kickhams club.
A judge ruled that 38-year-old Magee had carried out an 'unjustified' assault.
The ex-WBU welterweight title holder, from Eskdale Gardens in Ardoyne, will be sentenced next month.
