The 30-year-old forward went down 15 minutes into the game against Werder Bremen in a Bundesliga match.
With his country’s first match of the Qatar showpiece in just 12 days time, it appears that – according to L’Equipe – Mane’s issue is enough to see him miss out.
After the match on Tuesday, Julian Nagelsmann, coach of Bayern had said, “I can’t say anything for sure, he took a blow to the head of his shin.
“That’s an unpleasant spot, it radiates a bit into the muscles. I think he has to go to the X-ray to see if there is something there because it is splintering easily. But I hope that nothing is wrong. I can’t say anything for sure yet.”
