Kasimpasa suffered a blow to their dreams of a top-three finishing after suffering a 1-0 defeat against Sivasspor at the 4 Eylul stadium.
Yigit Incedemir scored a sixth minute goal to put the home side ahead and the relegation battling side were able to hang on for the remainder of the game to record a valuable three points.
A victory would have took the Istanbul minnows into joint fourth place alongside Basaksehir on 40 points but they were unable to make up lost ground.
On-loan Chelsea defender Kenneth Omeruo will start for Kasimpasa and put on a decent display making the highest number of interceptions (3) and the most tackles in defence (3).
The Nigerian international was also strong in the air making a total of five clearances but the Istanbul based side struggled going forwards and were unable to find the back of the net.
