Tyrone boss Mickey Harte has been hit with a series of injuries to key players ahead of Sunday's NFL clash with Armagh.
Midfielder Kevin Hughes (neck) is the latest player to be ruled out of the tie and joins wing-back Declan McCrossan (hamstring) and midfield partner Cormac McAnallen (knee) on the treatment table.
Harte also has a number of players on Sigerson Cup duty this week.
