McLoone missed the Ulster final against Derry after fracturing an eye socket in a club clash.
The dreadful injury came as he returned to the game after breaking an ankle in March.
He has featured for only about 40 minutes in the Championship so far.
McLoone played against Cavan and Tyrone but missed the opener against Antrim and the wins over Derry and Kildare.
Donegal team insiders are also confident that Christy Toye will also be in the squad after his super-sub role against Kildare.
He scored a goal just second after being brought on, and added a point to finish as his side’s top scorer.
Toye has endured a two-year battle to recover fitness from an achilles tendon rupture.
Michael Murphy, Rory Kavanagh and Kevin Rafferty also came through weekend club games unscathed.
Murphy did not start the All-Ireland quarter-final against Kildare because of a niggling hamstring while Kavanagh and Rafferty were both doubts for the game, but did play.
The captain is now said ti be very fit.Tags:
