Tony Donnelly and Fergal McCann have both stepped down from their positions within the Tyrone senior football management team.
Donnelly has been assistant manager to Mickey Harte since 2005, while McCann has been the senior team trainer throughout the same period.
Manager Mickey Harte paid tribute to the pair, who were part of the All-Ireland successes of 2005 and 2008, saying: “I wish to thank both men for their loyal support during the challenges we have faced over the past 10 seasons.
“They have given great service to Tyrone and to myself during their tenure and I wish both the best for the future"
County Chairman Ciaran McLaughlin also paid tribute to pair, saying: "The GAA in Tyrone owe a debt of gratitude to Tony and Fergal for their work over the past decade. Since becoming involved with the senior team in 2005, both played a major role in all our successes.
“On behalf of Coiste Chontae Tír Eoghain and the whole GAA community in Tyrone, I wish them every success."
Tyrone have won two All-Irelands, three Ulster titles and six Dr McKenna Cups during their time involved with the seniors.
