Heineken Cup Champions Toulouse will be without captain Thierry Dusautoir for their European Cup quarter-final against Biarritz Olympique.

The French back-row picked up a leg injury in his side’s Top 14 defeat to Racing-Metro at the weekend and underwent a scan on Sunday morning.

Guy Noves, who has led his side to four Heineken Cup triumph’s revealed he is not sure how long Dusautoir will be out of action but it is likely to be one month.

"There's only a small twist of the ankle and knee, but nothing that could raise doubts about his end to the season," said Noves.

"It's too early to know how long exactly he'll be out but it will not be more than one month.”
