Mane had to leave the pitch after 20 minutes of Bayern’s 6-1 win over Werder Bremen on Tuesday.

The forward is key to Senegal’s hopes at the World Cup, where they face the Netherlands in their Group A opener on Nov 21, followed by hosts Qatar and then Ecuador.

“Sadio Mane was hit on the leg, which caused him a little nerve pain. Nothing too serious and his participation in the World Cup should not be in jeopardy,” Toppmoeller told reporters.

Bayern coach Nagelsmann said the two-times African Footballer of the Year would undergo scans on the injury.

“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,” Nagelsmann said.

“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.”
