Aidan O’Shea has suffered up to seven concussions in career

Mayo footballer Aidan O’Shea has revealed he has suffered six or seven concussions in his playing career, two of them coming within weeks of each other in last year’s Connacht final and All-Ireland semi-final replay.

O'Shea's admission comes as Peter Robinson yesterday warned that "concussion can be fatal" after his teenage son Ben died during a schools rugby match this month four years ago.

The 2013 All Star clashed heads with Cillian O'Connor during last August's defeat to Kerry in Limerick, a collision which he felt had a "fairly significant" influence on the outcome of the game.
