Nigerian international Victor Osimhen has been sidelined for two weeks due to injury.
The 25-year-old sustained an injury during Galatasaray's hard-fought 3-2 victory away at Sivasspor in the Super Lig on Sunday, December 8.
Osimhen is set to miss three matches for Galatasaray, including games against Trabzonspor and Kayserispor.
The former Lille forward will also miss Galatasaray's Europa League clash against Malmo FF.
Osimhen's injury comes as a huge blow for Galatasaray, who have also lost Mauro Icardi for the remainder of the season.
The Super Eagles striker has netted 10 goals in 13 appearances for Okan Buruk's side since joining the club in early September.
