The Tyrone County Board have confirmed the departure of Stephen O'Neill from Tyrone's senior football management team.
O'Neill was appointed as forwards coach for the start of the 2018 campaign but he will not return to the role for the 2020 season.
The former Tyrone forward informed senior manager Mickey Harte over the weekend of his decision to step down.
He becomes the second member of the management team to depart after Peter Donnelly took up a strength and conditioning role with Ulster Rugby.
Tyrone were beaten by Kerry in their All Ireland semi final on the weekend before last.
