Tyrone midfielder Mickey Murphy has left the Red Hands' senior panel.
The Galbally clubman informed Red Hands manager Mickey Harte of his decision earlier this week.
The 29-year-old has been in and out of the senior squad for a number of years and was involved when the Red Hands won the Sam Maguire Cup for a second time in 2005.
Injuries have prevented him from nailing down a regular starting slot on the team and its thought his lack of game time recently has influenced his decision.
He won the man of the match award in last season's McKenna Cup final win over Derry while he came on as a substitute in Tyrone's championship win over Armagh that year as well.
After coming back from a month's holiday in Australia this January he started the National League encounter at home to All- Ireland champions Donegal when he lined out in midfield alongside Sean Cavanagh but he was replaced for the second-half of that game and that is the only taste of action he got in 2013.
