Bordeaux midfielder Jaroslav Plasil faces six weeks on the sidelines after suffering a knee injury.
The 34-year-old Czech international suffered the medial ligament problem during Bordeaux's 4-2 win at Guingamp on Saturday in a challenge with home striker Sloan Privat.
Plasil joins a lengthy Bordeaux injury list which also includes Cedric Carrasso, Milan Gajic, Nicolas Pallois and Gregory Sertic.
A message on the Bordeaux website read: "We wish a speedy and full recovery to our midfielder! Courage Jaro!"
