Tyrone could be without their captain Brian Dooher for their Bank of Ireland Ulster Senior Football Championship clash against Down in Omagh on May 22.
Dooher is receiving intensive physio on an ankle injury, which he picked up in a club game at the weekend.
Full back Chris Lawn (leg) is also a concern for manager Mickey Harte.
Brian McGuigan, currently overseas, is not expected to feature against the Mourne men.
