Tyrone will have to do without Aidan Cassidy for their Ulster SFC opener against Antrim on 23 May after the midfielder picked up an ankle injury in a club game at the weekend.
The 24-year-old dislocated his ankle while playing for Augher and will definitely miss the clash with the Saffrons according to Tyrone assistant manager, Tony Donnelly.
Kyle Cooney is also an injury concern due to a back problem.
