The Dublin footballers could face disciplinary action for delaying their run-out onto the pitch for yesterday's All-Ireland final.
The defending champions broke with protocol when they were four minutes late coming out of their dressing-room at Croke Park.
In what was the first of several flashpoints during the game, the Mayo players also emerged from the tunnel at the same time.
That lead to some pushing and shoving before the team photos.
The GAA's Central Competitions Control Committee will review the matter.
