Lenny Harbinson has stepped down as Antrim football manager in the wake of his side's Ulster quarter-final defeat to Cavan at the weekend.
The former county player, who managed St Gall’s of Belfast to the 2010 All-Ireland club title, was appointed manager in September 2017 on a three-year term.
In each of the three league campaigns, the Saffrons finished one place outside of promotion to Division 3, and failed to pick up a win in the Ulster championship in that time period, including a 14-point defeat to Tyrone last year.
His sole championship win came in the 2019 round qualifiers against Louth.
Cavan were made to work hard for their 0-13 to 0-09 victory on Saturday and trailed by a point at he interval before doing enough after to break to advance.
Harbinson informed the county board that he did not wish to extend his time in the hotseat.
"Lenny has been a good servant of Antrim GAA both as a player and a manager," a statement from the county board read.
"We would like to put on record our gratitude to Lenny and his management team for all the hard work put in over the last three years with Antrim Senior Football squad. We wish them all the best in the future."
