Clerc scored five tries during this year's Six Nations

France wing Vincent Clerc is expected to be out for up to six months after rupturing ligaments in his left knee.

Clerc collapsed without being touched during Toulouse's defeat to Clermont on Saturday, with TV replays showing his knee moving out of its socket.

He will now miss his side's Heineken Cup semi-final clash with London Irish next Saturday, 26 April, and France's two-Test summer tour of Australia.

Clerc starred for France in last year's World Cup and this year's Six Nations.

He has scored 20 tries in 33 games for Les Tricolores.
