Girondins Bordeaux midfielder Wendel has been ruled out of the rest of the season because of the knee injury he picked up in last month's League Cup final, the club said on their website.
"This kind of injury requires between six and eight weeks of treatment," the statement read.
St Etienne striker Ilan is doubtful for Saturday's home game against Toulouse, coach Alain Perrin told sports daily L'Equipe on Friday.
The final sprint in the Ligue 1 title race is becoming unbearable, according to Olympique Marseille's sports director.
"The stress is becoming unbearable. On our way back from the Nice game (on Wednesday), we were worn down," Jose Anigo told L'Equipe.
"It really wears you down. What will the (next) coach do, with which players, it is important for us to know," Armand told a news conference.
