Called Thursday by Didier Deschamps for the qualifications for Euro-2024, the central defender left the field a few hours later limping a little from the 21st minute of play, against Sporting Portugal (1-1), which eliminated the Gunners (2-2, first leg).
He would be hit in the back, according to several media.
The qualifying campaign for Euro-2024 in Germany begins against the Netherlands on March 24 in Saint-Denis and continues on March 27 against Ireland in Dublin.
Axel Disasi (25 years old, 3 selections), present in the list at the last World Cup, and the Niçois Jean-Clair Todibo (23 years old) are the two potential replacements. The decision will be taken in the coming days, after the league matches.
In defense, the Gunners had been called up alongside Eduardo Camavinga, newcomer Wesley Fofana, Théo Hernandez, Ibrahima Konaté, Jules Koundé, Benjamin Pavard and Dayot Upamecano.
