Armagh’s prospects of defeating Galway on Sunday have been dealt a blow after Rian O’Neill was unsuccessful in trying to overturn his dismissal from the round two defeat to Tyrone earlier this month.
Referee Martin McNally consulted with his linesman before issuing a straight red to O’Neill following an off-the-ball clash with Tyrone defender Cormac Quinn.
Tyrone went on to win the game 0-13 to 0-11 and the result could have a big bearing on the final outcome of Group Two on Sunday.
