Barcelona full-back Lucas Digne injured his thigh on international duty with France against Colombia on Friday.
The defender was forced off after 79 minutes of the 3-2 defeat in Paris and missed France's second friendly against Russia on Tuesday.
The Catalan giants confirmed the problem suffered by the Frenchman, who is in his second season at the Camp Nou:
