Ballon d'Or runner-up Sadio Mane was named in Senegal's World Cup squad by coach Aliou Cisse on Friday in spite of a recent injury.
Cisse, who captained Senegal at the 2002 World Cup, said he hoped the condition of the Bayern Munich attacker would improve within a few weeks and declared himself "really optimistic" that the injury would not require an operation.
The 30-year-old was diagnosed with an injury to his right fibula and will undergo further tests.
"I preferred to keep him in the group," Cisse told reporters.
"Sadio Mane is an important player in our squad, it is important to continue to follow his injury, hoping that in two or three weeks there will be progress. But we are really optimistic.
"We will give ourselves all the necessary means to allow Sadio Mane to recover."
Mane, who has scored 33 goals in 92 international matches, is joined in the squad by Abdou Diallo, another player who has recently missed game time due to injury as well as Everton midfielder Idrissa Gueye and Chelsea pair Edouard Mendy, Kalidou Koulibaly.
Senegal have been drawn in Group A and play the tournament opener against hosts Qatar on November 20, before going on to meet Netherlands and Ecuador.
