This weekend in the National Football League, Donegal play Dublin in the Division 1 semi final on Sunday.
Eoin Mc Hugh and Ciaran Thompson will not be available for the second run of the year to Croke Park.
McHugh has been ruled out of the game with a hamstring injury.
The Kilcar man suffered the injury in the second half of last Sunday's defeat to Monaghan in Castleblaney.
U21 Captain Thompson is due to go for surgery on a knee problem next week.
