Barcelona defender Samuel Umtiti has broken down while with France.
Sport says he suffered a foot injury during his time with the French national team - in a training session rather than in a game.
Umtiti did not play against Albania, a game which France won 4-1 on their way to Euro 2020 qualification.
With Umtiti injured - and Barca did not specify a return time - Ernesto Valverde has only three centre-backs.
Gerard Pique and Clement Lenglet, the first-choice duo, and Jean-Clair Todibo.
