Mustapha Yatabare scored the only goal as Sivasspor pipped Denizlispor 1-0 in Monday's Turkish Super Lig match but Ogenyi Onazi suffered an injury in the encounter.
Yatabare broke the deadlock just before the half-time, to take his league tally to 12 goals after 26 appearances so far this season.
The Mali international was in action for 70 minutes before he was replaced by Ivory Coast's Arouna Kone while Onazi was introduced just after the interval, but he could only manage 13 minutes of action before he was replaced due to injury by Cameroon's Marc Mbamba in the 59th minute.
