TYRONE boss Mickey Harte has made wholesale changes to his side for Sunday's Allianz NFL Division 1 semi-final against Kildare.
Cathal McCarron is the only survivor in defence from the team that lost to Kerry last week. Mattie Donnelly, usually a forward, is named at centre-back and Dermot Carlin and PJ Quinn make their first appearances of the season.
Conor Gormley, who impressed off the bench last week, is back in the starting line-up and Martin Penrose replaces Ronan O'Neill (hamstring) in the attack.
Kildare, meanwhile, include four of the team who beat Longford in the Leinster U-21 final for the Red Hands showdown.
U-21 'keeper Mark Donnellan takes over in goal from Shane Connolly, Paul Cribbin retains his place in the half-backs and Daniel Flynn and Niall Kelly return at the expense of Willie Groome and Eamonn Callaghan.
Cork hurlers have made two changes to their defence ahead of their Division 1A relegation battle with Clare.
Shane O'Neill comes in at corner- back and Willie Egan at wing-back to replace Killian Murphy and Cian McCarthy.
Galway's Niall Burke (21) has been ruled out of the hurling league semi-final against Kilkenny after surgery on a calf problem, but could be back in time if they make the final.
