Police were called to the Stadium of Light following claims Oxford United goalkeeper Jack Stevens was headbutted at half-time in the U’s 3-1 League One defeat at Sunderland.
Oxford boss Karl Robinson admitted he did not see the incident which happened in the tunnel during the break.
“We are waiting for the police to come, one of my goalkeepers was headbutted at half-time,” he told BBC Radio Oxford.”I don’t want to use names, it’s not right to do that.” (BBC)
