Galatasaray defender Aurelian Chedjou has been ruled out with injury for two weeks according to NTV Spor.
The Cameroon international picked up a hamstring injury during the 1-0 win over Konyaspor on Friday.
Chedjou will be unavailable for the Mersin İdman Yurdu and Gençlerbirliği games in the Süper Lig over the next two weeks.
The experienced defender could return in time for the derby match Beşiktaş in the penultimate week.
Hakan Balta and Semih Kaya are likely to fill in as the Lions centre-backs following injury to Chedjou.
Koray Günter is another defensive option for Hamza Hamzaoğlu.
Galatasaray have kept clean sheets in their last three consecutive league games with Chedjou in the lineup.
