Tiernan McCann has become the latest player to leave the Tyrone squad.
McCann, 30, was a sub last year coming on in four of Tyrone’s five Championship games, including the All-Ireland final win over Mayo.
He also hit three crucial points from play in the Ulster semi-final victory over Donegal.
The Killyclogher man is the fifth player to depart the Tyrone squad over the last number of weeks.
Ronan O'Neill, Mark Bradley, Hugh Pat McGeary, and Michael Cassidy have all left Feargal Logan and Brian Dooher’s squad as they gear up for the defence of their All-Ireland crown.
The quartet saw very little game time last year bar Bradley, who started the Ulster final win over Monaghan, and hit two points.
McCann joined the Tyrone panel in 2013, and made his Championship debut the following year in an Ulster preliminary round game against Down.
The flying wing back was a virtual ever present under Mickey Harte in the Tyrone half back line and made 105 appearances for the county, including 38 in the Championship, hitting 4-36 in total.
