Nottingham Forest midfielder Cheikhou Kouyaté "could be out" of Senegal's World Cup last 16 tie against England on Sunday evening.
The 32-year-old was stretchered off during Senegal's opening group game against the Netherlands on November 21 and has not featured for his country at the tournament since.
They are now preparing to face England in the round of 16 but could be without Kouyaté, who has not trained this week ahead of the match. It is unclear whether he will be able to return for Forest when domestic football gets back under way later this month.
