Besiktas’s Gokhan Tore, Ersan Gulum and Tolga Zengin are all a doubt for this weekends Super League clash against Istanbul rivals Kasimpasa.

Manager Slaven Bilic returned to Istanbul to lead first team training at the Nevzat Demir training facility.

First choice goalkeeper Tolga was only able to participate in light training due to his shoulder injury. Ersan Gulum missed training due to a tight hamstring while Tore did not take part because of pain in his left knee.

Mustafa Pektemek, İsmail Köybaşı, Oğuzhan Özyakup and Tomas Sivok only participated in light training as they played international games on the weekend.

Ugur Boral will go under the knife tomorrow. The experienced winger suffered a knee injury last week during training.

Besiktas face Kasimpasa on Sunday in the league.
