Ulster manager Brian McEniff has strengthened his squad ahead of Saturday's Railway Cup football final.
Tyrone stars Sean Cavanagh, Philip Jordan, Brian Dooher and Stephen O'Neill have been added to the Ulster panel after returning from International Rules duty.
Armagh attacker Ronan Clarke will also be involved in the M Donnelly Interprovincial decider against Leinster under the Parnell Park floodlights.
The manager revealed that the decision to strengthen the squad was left to the players who featured in the semi-final win over Munster, and the outcome was a unanimous yes.
"I was very proud of the players for the decision they made, even though they knew that it might cost some of them their place," said McEniff.
"The lads gave me their best against Munster, and it was their success that got us to the final."
Ulster turned on the style in the second half to send Munster crashing to a 2-13 to 0-9 defeat at Crossmaglen and set up a repeat of last year's final, which the northern province won in Paris to make it 27 titles in all, 12 of which have been lifted under the management of McEniff.
Leinster, with 26 inter-provincial titles to their credit, can draw level on Saturday evening.
Tyrone defender Ryan McMenamin is still struggling with a chest infection which limited his involvement in the International Rules series in Australia, while Ulster will also be without Cavan's Anthony Forde and Marty McGrath of Fermanagh, both of whom have Ulster Club Championship commitments this weekend.
