Barcelona defender Jeremy Mathieu has reportedly suffered a knee injury while on international duty that could force him out of the upcoming Clasico against Real Madrid.
According to AS and Mundo Deportivo (h/t Football Espana), Mathieu left the pitch during France's 4-2 win over Russia just eight minutes after coming on. While he didn't need a stretcher, he may have torn his meniscus.
Per the report, he's set to undergo tests as soon as he returns to Barcelona.
