The Chelsea centre-half has left Clairefontaine and
returned to London for further treatment on the knock he picked up at
Stoke on Saturday
The Chelsea defender picked up a knock in Saturday's Premier League loss at Stoke and will miss what are two crucial 2017 European Championship qualifiers for his country.
In a further blow for the French, an injury has also ruled Athletic Bilbao centre-half Aymeric Laporte out of the Thursday's meeting with Northern Ireland in Guingamp and Sunday's crucial clash with Macedonia in Skopje.
