According to RB Leipzig, Christopher Nkunku tore the lateral collateral ligament of his left knee.
Nkunku was forced to pull out of the World Cup on Tuesday after suffering an injury in a practice clash with Real Madrid midfielder Eduardo Camavinga.
The 25-year-old has been replaced by Didier Deschamps for another player who plays in the Bundesliga, Eintracht Frankfurt’s Randal Colo Muani.
On Saturday, Leipzig confirmed the nature of Nkunku’s injury, but could not give a timeline for his return.
A statement on the club’s website read: “Christopher Nkunku tore his LCL in his left knee while training with France on 15 November in Paris.
“It is not yet clear how long he will be out and there are different treatment options for this injury. We will give Cristo the best possible support so that he can return as soon as possible.”
Nkunku has scored 16 goals in 22 games this season and Die Roten Bullen will be looking to get him back as soon as possible as Leipzig currently sit third in the Bundesliga, six points behind leaders Bayern Munich.
Leipzig also announced that Croatian defender Josko Guardiol will not miss the World Cup despite breaking his nose in a recent victory over Freiburg, while midfielder Konrad Laimer returned to training after suffering an ankle injury in September.
