Monaghan have been dealt a significant blow with full-back Drew Wylie set to miss the rest of the season with a suspected cruciate ligament injury.
Wylie sustained the injury while playing for Ballybay in a club match in the week after their Ulster quarter-final win over Cavan.
Wylie, an All-Star nominee, has developed into one of the most formidable full-backs in the game and his loss will be sorely felt.
Monaghan face Fermanagh in an Ulster semi-final this weekend and Colin Walshe, who himself has recovered from a cruciate ligament rupture sustained in last year's All-Ireland quarter-final defeat to Dublin, is a likely replacement
Elsewhere, Roscommon manager John Evans is hoping that a few minor injuries will clear up in time for Saturday's Connacht semi-final with Sligo, but he says defender Donal Ward is fit to play.
Kilbride (hamstring), Ultan Harney (facial), Kevin Higgins (shoulder), Conor Daly (eye) and Mark Healy (ankle) all face a race against time to make the Markievicz Park game.
However, the Rossies are boosted by the return of Donal Ward after injury. Ward, a prison guard, sustained a shoulder injury at work in Cloverhill Prison a little over a week ago, but he has already returned to training.
Elsewhere, Conor Twomey captains the Cork U-21 side that takes on Waterford in Páirc Uí Rinn tomorrow.
