John Lundstram and Borna Barisic could be axed after just one year at Trabzonspor.
The former Rangers pair joined the Turkish side on free transfers last summer but are now facing uncertain futures.
Left-back Barisic has hardly featured, while midfielder Lundstram has been criticised for his performances.
Reports in Turkey suggest Barisic's contract may even be terminated.
Trabzonspor manager Fatih Tekke needs to cut seven players from his squad this summer due to a quota of 12 foreign players, with 14 currently in the squad and more returning from loans.
The club are also planning to sign another five players in the transfer market.

Barisic and the club are reportedly in discussions over cancelling his contract, while Lundstram, 31, is at risk of being moved on due to his age.
Both players signed three-year deals with Trabzonspor last year, so their departures may not be straightforward.
The team's disappointing European campaign, which saw them crash out of both the Europa and Conference Leagues, and a poor start to the league season have contributed to the need for a squad overhaul.
However, they did manage to recover somewhat, finishing seventh in the league and reaching the final of the Turkish Cup.
The team went through three permanent managers over the course of the season, with Tekke only appointed in March.
Barisic's season was further disrupted by a loan move to Leganes in Spain in January, which was cut short by a serious injury in his first game.
Ex-Man City star Stefan Savic, Edin Visca, and Anthony Nwakaeme are also said to be likely candidates for summer sales.
