Lyon — Former France international fly-half Frederic Michalak said on Monday he would retire from rugby at the end of the season.
The 35-year-old, who made 77 appearances for France and currently plays for Top 14 side Lyon, said he was no longer confident he could withstand the rigours of top-class rugby.
"After thinking long and hard about an offer from the club [to stay], I will end my career at the end of the season," he said. "I still have that love for the game but this is a sport where you have to be at 200% physically.
"I am 35 … so I said this would be a good year to stop."
Michalak spent seven years at French powerhouse Stade Toulouse and also enjoyed stints at the Sharks.
He will forever be remembered in France for his quarterfinal substitute appearance in the 2007 World Cup when he set up the winning try for Yannick Jauzion against New Zealand in Cardiff.
