Tyrone manager Mickey Harte has a number of injury concerns ahead of Sunday's Ulster SFC semi-final against Donegal.
A series of injuries, brought on by a heavy schedule of club games, is threatening to derail the Red Hand county as they bid to lift the Anglo-Celt Cup for the first time since 2003.
Both Tommy McGuigan (broken wrist) and Niall Gormley (broken jaw) injured themselves in recent club fixtures and are potentially facing two-month lay-offs.
McGuigan and Gormley both made their championship debuts in Tyrone's first round win over Fermanagh, scoring seven points between them.
The attacking duo are certain to miss this weekend's clash with Donegal, while two more forwards - Ger Cavlan, who is suffering from a knee injury, and Stephen O'Neill, who has tendonitis in one of his knees - both doubtful for the Clones test.
League champions Donegal should be able to call on star forward Brendan Devenney for Sunday's clash, as the St. Eunan's clubman has been making good progress with a stomach muscle injury.
Half-forwards Ciaran Bonner and Michael Hegarty are both on the mend after sitting out training last week. Bonner had his tonsils recently removed, while Hegarty is recovering from knee surgery.
