Sadio Mane suffered a World Cup injury scare during Bayern Munich’s match with Werder Bremen at the Allianz Arena.
The 30-year-old suffered the problem early in the match with just 15 minutes on the clock, and was assessed by medical staff before being replaced by Leroy Sane.
Bayern manager Julian Nagelsmann says Mane “took a knock to the head of his tibia. It’s always uncomfortable. He has to have an X-ray. I hope nothing is wrong.”
The injury scare comes just 13 days before Senegal kick their World Cup campaign off with a match against the Netherlands.
Mane is Senegal’s record scorer with 34 goals and scored the decisive penalty as his country beat Egypt to win the Africa Cup of Nations earlier this year.
In Qatar, Senegal are in Group A along with the host nation, Ecuador and the Netherlands.
Aliou Cisse has named his final 26-man squad for the tournament.
Mane is joined in the group by Chelsea’s Edouard Mendy and Kalidou Koulibaly, as well as Everton’s Idrissa Gueye.
Cheikhou Kouyate and Ismaila Sarr have also made the squad.
