All-Ireland winning Galway hurling manager Micheál Donoghue has stepped down after four seasons in charge of the Tribesmen.
Donoghue, who had led his native Clarinbridge to the 2011 All-Ireland club title, was appointed in late 2015, following a vote of no confidence by the players in former boss Anthony Cunningham.
In Donoghue's first campaign, Galway were beaten by a point in the All-Ireland semi-finals by eventual champions Tipperary.
However, they reversed that scoreline at the same stage against the same opponents in 2017, after claiming the Leinster title, and went on to beat Waterford in the final by six - it was the first time the Liam MacCarthy Cup had gone west since 1988.
Earlier in the year they had clinched the Allianz Hurling League crown in style with a 16-point dismissal of Tipp in the final.
The defending champions retained their Leinster title and made it back to the All-Ireland decider last year but were out of sorts in the first half against Limerick and their furious fightback fell one point short.
Donoghue was given a two-year extension to his term in charge last November but an injury to key forward Joe Canning didn't help their cause this summer and they were the surprise casualty from the Leinster round-robin stage.
A failure to rack up a score against Carlow and defeat to Dublin in Parnell Park ended their Championship early despite amassing five points and suffering just one defeat in four games.
In a statement to Galway Bay Fm, Donoghue said: "After four seasons, we feel the time is now right to hand on the opportunity to a new management team."
Galway County Chairman Pat Kearney told RTÉ Sport this morning that the announcement "came as a surprise", and said "hopefully by the 1st of October we'll have a man in place."
He added: "I want to publicly acknowledge, on behalf of all involved in Galway GAA, Micheál's contribution, and that of his selectors and backroom team, since taking up the post."
