Beşiktaş defender Tomas Sivok has been closely linked with a move to Kasımpaşa according to Eurosport TR.
The Czech Republic international has missed much of the season due to injury.
Sivok is expected to leave Beşiktaş following the arrival of Swedish international defender Alex Milosevic.
The experienced defender has also been linked with PAOK and Leicester City.
The 31-year-old has spent seven seasons at the Istanbul based club but has found himself on the fringes of the squad this season due to injuries.
The Czech Republic international joined Beşiktaş from Udinese in July 2008 for €5 million.
The defender has made 12 appearances for the Black Eagles this season.
Sivok has 48 international caps for the Czech Republic.
Kasımpaşa are currently 11th in the Süper Lig and coached by Dutch manager Jan Wouters.
