Peter Leahy has stepped down after three years as manager of Mayo's ladies senior football team.
The Westmeath native is joining the high-profile backroom team of new Meath Under-20 manager Bernard Flynn. Former Royal stars Graham Geraghty and Graham Reilly are also on board.
Leahy told MidWest Radio that the decision was made with a "tinge of sadness".
"An opportunity arose," he said. "The last year with Mayo was exceptionally tough but I had a year left in my contract that I was going to honour.
"It transpired the opportunity came up to work with a legend like Bernard Flynn.
"I felt I needed a change and I think at the end of the day it will be healthy for the players to make a change at this stage."
Mayo reached the All-Ireland semi-finals in 2019, Leahy's second campaign in charge but his reign was overshadowed by the dramatic departure of 12 players from the panel in July 2018.
The players, who included now AFLW star Cora Staunton, told RTÉ Sport at the time that they left due to a "toxic" environment in the camp.
Leahy, however, insisted that the group's unhappiness had stemmed from disagreements with his team selection, and he was backed by the county board who said it had been "a move designed to wrestle control of the senior team from the management".
Mayo LFGA attempted to expel their now 21-in-a-row club champions Carnacon from that year's championship over the walkout of eight of their players but the Connacht Council overturned the decision.
No player from Carnacon has represented the county since.
