Mr. Michael Darragh MacAuley:

Yes. Acquired Brain Injury Ireland has been working with the GPA on this matter. In terms of the GAA, we saw the Rory O'Carroll incident in the All-Ireland final. Obviously, he was in no state to play. He could have been on a beach in Spain and he would not have known the difference. There were no substitutes left, though, so he could not leave the pitch. He was left to wander around it and was of no use to anyone. Like blood substitutes, perhaps there should be something like a brain injury substitute. It is not a matter for this committee, but perhaps the GAA should consider it.
