Geelong premiership star Zach Tuohy will retire at the end of the AFL season as the competition's Irish games record holder.
Tuohy, 34, will hang up the boots at the end of the finals campaign after more than 280 games with the Cats and Carlton.
Tuohy told his teammates of his decision on Tuesday and announced it in a video statement to Geelong members on Wednesday
"While there's a lot of footy left to play this year, I just wanted to take this opportunity to thank you all for your support," Tuohy said.
"I knew when I came to the Cats I was in for a treat. I don't think I fully appreciated just how much of an incredible journey it was going to be.
"There's a lot of work left to do this year but I just wanted to thank you for everything.
"Geelong, the club and the city, has been incredible for me and my family.
"I consider myself a Geelong person forever off the back of your support.
"A lot of work left to do - I look forward to seeing everyone this weekend - but 2024, that'll do me."
Tuohy attracted attention from AFL recruiters in 2009 and was lured by Carlton out of Portlaoise in County Laois in 2010.
He became an accomplished defender and moved to Geelong at the end of 2016, before featuring in the Cats' 2022 premiership alongside fellow Irish player Mark O'Connor.
The pair were the second and third Irishmen to win premierships after Sydney's Tadhg Kennelly (2005).
Tuohy is only the second Irish player to play more than 200 AFL/VFL games and passed the late Jim Stynes' record of 264 appearances last year.
He will play his 287th game when the Cats host West Coast at GMHBA Stadium on Saturday.
"Zach has been a skilful, durable and flexible player across his eight seasons in the hoops," Geelong football manager Andrew Mackie said.
"He will depart as the Irish games record holder, which is a remarkable achievement for someone who made the decision 15 years ago to leave home to travel across the world to play our game.
"He is a loved and respected teammate and has contributed greatly to the environment of our club."
Meanwhile, luckless ruckman Sam Naismith is also hanging up the boots after yet another ACL injury.
Naismith managed 30 games in 10 seasons at Sydney because of recurring knee injuries, including three ACL ruptures.
The 32-year-old joined Richmond this season as a delisted free agent, playing two AFL games before suffering a career-ending setback in the VFL.
"This has been the best year of my football career," Naismith told teammates.
