Senegalese international Sadio Mane will undergo a medical examination after suffering a knee injury during the match Bayern Munich won over Werder Bremen with an impressive six goals to one.
And Mane was injured in the 16th minute and he left injured to enter the match, instead of him, to Roy Sani.
It happens just 13 days before the start of Senegal's opening match in the 2022 World Cup against its Dutch counterpart.
Bayern Munich coach Julian Nagelsmann said: "He's going to have an x-ray to find out exactly what happened. He hit the tibial bone [the shin], it's a very painful and sensitive place."
And when he was injured from a stadium, Mane did not go to sit on the bench and went directly to the tunnel leading to the exit from the stadium to receive the necessary treatment.
The former Liverpool star is one of the most important elements in the Senegal squad, the African Cup of Nations champion, who will face the Netherlands in its opening match in Group A on November 21, before playing against the host country Qatar, and then Ecuador.
Because of Mane's decisive penalty, Senegal beat Egypt on penalties in the final match of the African Cup of Nations, so Senegal won the continental title for the first time in its history, earlier this year.
Despite concerns about the two-time African Footballer of the Year award, Bayern Munich assistant coach Dino Topmüller later downplayed the extent of the injury.
"Nothing is too dangerous, and his participation in the World Cup should not be in danger," he said.
Jamal Musiala scored Bayern Munich's first goal in the match after five minutes, but Werder Bremen quickly equalized through Anthony Young.
Bayern Munich responded harshly, scoring three goals in just eight minutes (a goal by Leon Goretzka, and two for Gnabry), to advance the Bavarian giant by four goals to one goal after just 30 minutes.
Things could have been worse for the away team, but goalkeeper Jiri Pavlenka saved Eric Maxim Chubo-Moting's penalty.
Bayern's performance declined in the final stages of the match, before Gnabry scored his third goal in the 82nd minute, and young French player Matisse Tal added the sixth goal.
