Paddy McKeever will not feature in this weekend's Ulster final having failed to recover from his hamstring injury in time to face Donegal.
Martin O'Rourke comes into the side for McKeever while John McEntee also returns to the forward line after missing the semi-final with a slipped disc. Stephen Kernan is the player to make way.
Donegal, who are bidding to stop Joe Kernan's side winning their third Ulster title in succession, are due to name their side later this evening.
Meanwhile, Tyrone have been forced into another two changes for their qualifier against Laois on Saturday.
With Conor Gormley and Colin Holmes joining the growing list of walking wounded in the All-Ireland champions squad following the win over Louth a fortnight ago, Ciaran Gourley and Kevin Hughes have been drafted into the starting line-up.
Footballer of the year Stephen O'Neill had hoped to feature but is still struggling with injury and will again watch from the sidelines.
