Toulouse are set to welcome back six internationals for the final round of the Top 14 regular season, including Thierry Dusautoir.
The France skipper has been sidelined with as bicep injury since January but the Toulouse management hope he will be able to play in Saturday's crunch clash at home to Grenoble.
Fellow French internationals Louis Picamoles, Yannick Nyanga and Yann David as well as former All Black Luke McAlister and Springbok prop Gurthro Steenkamp are also hoped to be fit.
"We're optimistic about their return this weekend," said manager Guy Novès.
"We hope there won't be bad news this week.
"Concerning Thierry Dusautoir, Tuesday will be an important day because they will test themselves for real."
