Kasımpaşa defender Orhan Şam has been ruled out for six months after sustaining an injury during training.
Şam tore his right Achilles tendon during training and had to be rushed to hospital.
Kasımpaşa are currently in 10th place and take on Eskişehirspor next.
The Istanbul based side are safe from relegation but recently appointed manager Önder Özen has led the team to two consecutive victories over the past two weeks.
The former Beşiktaş director of football replaced caretaker manager Jan Wouters who will return to his position as head of youth development.
Former Kasımpaşa manager Shota Arveladze quit his job after his side lost 2-1 following his touch of class in allowing the opposition to score.
Ryan Donk put Kasimpasa 1-0 ahead against Konyaspor but but the visitors had stopped playing because of an injury to Kasimpasa attacker Ryan Babel.
However, Arveladze ordered his side immediately allow Konyaspor to score allowing Hasan Kabze to stroll through to score immediately after the re-start.
Wouters was expected to take charge until the end of the season but Özen was appointed head coach instead.
