Armagh dug in superbly in Clones last Saturday evening to rescue a draw against Monaghan in their Ulster semi-final.
Points from Jamie Clarke, Stefan Campbell and Rory Grugan in the last five minutes ensured Sunday’s replay.
Last Saturday’s game was a typically tense and tight Ulster derby.
The two sides were level seven times in the game, and neither ever got too far ahead of the other.
While Armagh will have been the happier of the two at full-time, given the way they came back, this remains an extremely hard one to call.
Monaghan boss Malachy O’Rourke has made two changes, both in attack, from the drawn game.
Chris McGuinness, who made a positive impact from the bench last weekend, and Paudie McKenna both come into the half-forward line.
And Jack McCarron and Pádraig Donaghy dropping to the bench for what should be a close encounter.
Armagh have Brendan Donaghy, Andy Mallon and Kieran Toner available again after serving one-match bans in the drawn game.
Monaghan scored just six points from play in last week’s stalemate with Armagh.
