Paris - Scotland lock Richie Gray will play his first game since October as his French Top 14 side Toulouse host Grenoble on Sunday.
Gray, 29, who has 65 international caps made his last club appearance in a victory over Agen three months ago, suffering a hip injury which needed surgery. At the time of that setback, Gray was returning from a hip problem.
He also missed four months of action last season with a back issue.
The second-row's last Test came in March's Six Nations success over Italy in Rome when he came onto the field to join his brother Jonny among the visitors' forwards.
Toulouse can move to the top of the table with a win at Stade Ernest-Wallon after leaders Clermont lost 24-16 to Castres on Saturday.
