England great Jonny Wilkinson is due to undergo a minor operation to relieve inflammation round his groin area on Saturday.
The 33-year-old flyhalf should be able to play in Friday's Top 14 top versus bottom clash with Mont-de-Marsan, but will then have a week's rest after the operation.
* Meanwhile Toulouse's Georgian prop Vasil Kakovin will be sidelined for three weeks after cracking a rib in the 9-5 defeat to Leicester.
Kakovin came on for South African Gurthrö Steenkamp in the closing stages of the game which sealed the four-time European Cup winners' exit from Pool Two, but lasted just seven minutes on the snowy surface at Welford Road after a crunching encounter with Italian Martin Castrogiovanni.
Two clubmates - fellow Georgian Jaba Bregvadze and Jean-Baptiste Poux meanwhile were in the gym as they look to shrug off fitness concerns ahead of Friday's Top 14 meeting with Biarritz.
