Tyrone’s Ronan O’Neill has been ruled out of Sunday’s Ulster SFC quarter-final against Donegal due to a hamstring strain.
The 20-year-old attacker, who missed most of last season with a cruciate injury, damaged the hamstring in training.
Meanwhile, midfielder Aidan Cassidy, who has been sidelined with an ankle injury since the Allianz Football League final against Dublin, trained at the weekend, while Dermot Carlin and Justin McMahon are expected to be fit for the clash in Ballybofey.
And manager Tony Donnelly confirmed that skipper Stephen O’Neill will be fit to lead the Red Hands this weekend following an ankle injury.
For Donegal, Karl Lacey is back training and available following a hip injury that kept him out of the Allianz League campaign.
Elsewhere, Mark McHugh continues to be troubled by a long-term groin injury and manager Jim McGuinness may not risk him from the start this weekend.
Otherwise Donegal are at full strength.
