Arsene Wenger will be left sweating on the fitness of the centre-back ahead of Saturday's game with Sunderland, after his withdrawal from les Bleus' squad
The 26-year-old centre back is the latest in a line of injuries for Gunners boss Arsene Wenger, who will also be without Jack Wilshere, Bacary Sagna and Emmanuel Frimpong for the season's curtain raiser against Sunderland on Saturday.
"Everybody has arrived this morning and everybody is in good health," said new France boss Didier Deschamps.
"We have a problem with Laurent Koscielny who has a problem with his calf. He will be examined this afternoon but its seems difficult to play him on Wednesday."

Mikel Arteta missed the Gunners' 4-0 win against FC Koln on Sunday, while youngster Alex Oxlade-Chamberlain has also withdrawn from Roy Hodgson's England squad after picking up an ankle problem.
Wenger will be left sweating on the availability of Koscielny for the visit of the Black Cats, but France boss Deschamps has resisted the opportunity to replace the defender.
"It's not much of a concern to have 21 players," he added.
"I am not going to call anyone else up. Right now we have enough players in that position. Certain people aren't here because of different reasons - also through injury.
"I will have the choice over making the best selection possible in this area. Talent has no age. Experience is not picked up over night.
"It takes time, a series of games. With the withdrawal of Koscielny, three defenders are left. Two will make their debuts, which will help us take a look at them"
The three defenders in contention are Mamadou Sakho, Mapou Yanga-Mbiwa and Raphael Varane.
