Toulouse have been dealt a double injury blow with the news that forwards Romain Millo-Chluski and Gillian Galan have been sidelined.
French international lock Millo-Chluski suffered a torn elbow muscle in Friday's 9-3 loss to Oyonnax. He should be out for six weeks.
Toulouse are already without veteran Argentine second-rower Patricio Albacete while Yoann Maestri is away on Six Nations duty with France. Joe Tekori, Edwin Maka and Grégory Lamboley are the only available options for this weekend's clash with Montpellier.
Meanwhile, hulking number eight Galan will miss about three weeks because of a knee injury suffered in Oyonnax.
A scan on Monday confirmed that nothing is broken but revealed a sprain, meaning Galan will miss the upcoming Top 14 games against Montpellier and Toulon.
