Manchester United keeper Roy Carroll was hit on the head by an object thrown from the crowd during the FA Cup clash with Everton at Goodison Park tonight.
Wayne Rooney’s return to his boyhood club for the first time since his transfer to United had raised fears of security problems.
And, with United leading 2-0 in the 70th minute of the fifth round tie, Northern Ireland keeper Carroll was struck by a missile hurled out of the crowd behind his goal.
Carroll collapsed to the turf and it took a couple of minutes of treatment to get him back into action.
A coin and a mobile phone were retrieved from the pitch and handed to police by the fourth official.
