Oisín Mullin has accepted a position to play with the Geelong Cats.
Mayo GAA has announced the move on social media.
They say they want to wish Oisín the best in his new endeavour and thank him for all the memories.
Oisin made his debut with Mayo on the 25th January 2020 in the NFL against Donegal.
Oisin is a two-time young footballer of the year.
Geelong's head of list management Andrew Mackie welcomed Mullin's arrival and addressed the player's previous decision not to sign for the 2022 season.
"As a club we appreciate the magnitude of moving overseas and understood Oisin's reasons for remaining in Ireland and not joining us for this season," he said.
"We are thrilled he will now join the Cats for season 2023, he is a gifted talent, however most importantly a quality person who will be a great addition to our playing squad.
"Oisin has had another impressive season with Mayo and we are looking forward to welcoming him and his partner Jess to the club and to Geelong."
