William Barthua has announced his retirement from rugby league, aged 30.
The Toulouse half-back has made more than 200 professional appearances, and has featured for France in two World Cups in a 13-year long career.
He also featured for Catalans Dragons and London Broncos.
“It was a very difficult decision to make,” he said.
“I will have to accept it in order to move forward because great things await me.
“Thank you to Toulouse Olympique for allowing me to continue my passion. I wish the TO club to achieve the goals they set for themselves. Some took the elevator to the Super League, but taking the stairs makes you feel stronger.”
Toulouse president Bernard Sarrazain said: “It’s obviously a disappointment to lose a player like William, but we fully understand his choice.
“Thank you to him for what he has brought to the club in recent seasons; our door will always be open and I wish him the best for the future.”
