Senegal forward Sadio Mane has undergone surgery on a knee injury he sustained playing for Bayern Munich and will miss the World Cup.
On Tuesday, Senegal's football federation said Mane, 30, would miss their "first games" at the tournament.
But a further MRI scan was completed on Thursday that showed surgical intervention was needed.
Mane was forced off during Bayern's Bundesliga win over Werder Bremen on November 08, reports BBC.
Bayern have confirmed the player "underwent successful surgery" on Thursday, to attach a tendon to the head of his right fibula
"The forward will begin his rehab in Munich in the next few days," the club added.
Senegal start their World Cup campaign against the Netherlands on Monday. The West Africans are in Group A with games against hosts Qatar (November 25) and Ecuador (November 29) to follow.
Two-time African Footballer of the Year Mane is Senegal's talisman, having scored the winning penalty when the Teranga Lions became continental champions for the first time in February, defeating Egypt in a shootout in the Africa Cup of Nations final.
Within two months Mane had repeated the feat, netting the decisive spot-kick as Senegal beat Egypt - in a game that again pitted him against then Liverpool team-mate Mohamed Salah - on penalties in a play-off to qualify for Qatar.
