Jules Koundé, a player for FC Barcelona, suffered a muscle injury during his team's match against Villarreal in the 17th round of the Spanish league. He left the field in the 79th minute after experiencing severe pain that caused him to fall and require medical attention.

The French defender pointed to the bench, indicating that he was unable to continue playing, which prompted head coach Hans Flick not to take any risks and to substitute him with his teammate Marc Casado, who took up the right-back position as he had previously done in the match against Guadalajara in the Copa del Rey.

The newspaper "Mundo Deportivo" pointed out that the injury may have resulted from intense physical effort during a defensive play, confirming that this is Koundé's first injury this season, despite his absence for over a month at the end of last season due to similar muscle problems.

Barcelona is awaiting the release of the official medical report to determine the nature of the injury and the expected duration of the absence, especially with important upcoming matches approaching, most notably the Catalonia derby against Espanyol and the Spanish Super Cup competitions.
