Former France international Jerome Guisset will bring his 12-year association with Catalans Dragons to an end when he leaves the club at the end of the season.
Guisset is one of the few remaining links with the Perpignan club's entry into Super League, having joined them as a player from Wigan in time for their inaugural season in 2006.
A second rower who also played for Canberra and Warrington as well as France, Guisset featured in the Dragons' historic opening game, a 38-30 win over Wigan at Stade Aime Giral, and went on to make a total 269 Super League appearances before hanging up his boots in 2010.
He then began his coaching career under Trent Robinson and also assisted former team-mate Laurent Frayssinous and more recently current boss Steve McNamara.
Guisset, who has given no indication of his future plans, said: "I would like to thank the chairman, Bernard Guasch, as well as the board of directors. I will be forever grateful for the opportunity the club has given me.
"Leaving this club has been a tough decision to take but, after seven years as an assistant coach, I feel now is the right time to move on to the next chapter in my career and start a new experience.
"I spent some great years with the Dragons, first as a player, then in the coaching staff and also with the club's reserve team. I'm extremely proud to have given my best for this jersey and this club over the last 12 years."
Catalans chairman Bernard Guasch said: "Jerome is at a turning point of his life and I understand and respect his decision.
"He will discover a new environment and start a new experience, maybe to come back stronger at the club. Jerome is one of the legends of our short history, who has always given his best for the club, as a player or as a coach. The entire club wish him all the best for the future."
