Donnelly is to take up a full-time position with the Red Hands next month, following a three year spell with the Cavan county board.
But he will not be working exclusively with Mickey Harte’s senior team. The Coalisland Fianna clubman, who won All-Ireland medals as a player with Tyrone at all levels, is to coach all teams in the county from his base at the Garvaghey Centre.
The 32-year-old links up once again with Harte, having been a player under the Errigal Ciaran man at under-age and senior level.
He captained Tyrone to Ulster U21 success in 2003 and won a senior All-Ireland medal in the same season, before savouring Sam Maguire Cup glory for a second time as a squad member two years later.
“He will have a brief with the senior team but he will be working along with all teams in the county as strength and conditioning coach,” said county PRO Eunan Lindsay.
Donnelly, who has been working as full-time Athlete Development and Skills Coach with the Cavan county board, is highly regarded in the Breffni county, and is credited with a major input into the county’s four-in-a-row sequence of Ulster U21 titles.
