Ulster champions Armagh meet Tyrone at Croke Park in the second Bank of Ireland All-Ireland SFC semi-final as the two Northern rivals vie for a chance to oust holders Kerry from their throne later this month.
Mickey Harte's men will be anxious to avenge their controversial provincial final defeat last month when they seemed to be cruising to victory before poor refereeing decisions cost them two players.
They were four points up when substitute Peter Canavan was harshly singled out in a mass melee. From that point it was all Armagh and the subsequent loss of Stephen O'Neill further eroded any chance they had.
However, this time out Harte will have his men briefed on the importance of discipline against the might of Armagh.
Joe Kernan's men will no doubt be up to anything Tyrone can muster but can they reproduce a winning performance against a full Tyrone XV?
There are undoubted match-winners on both sides, with the likes of Tyrone's O'Neill and Owen Mulligan and Steven McDonnell and Ronan Clarke for Armagh.
On the day it could be boil down to desire and discipline, and Tyrone are unlikely to be found wanting twice.
