Skysports.com understands that Kilmarnock are willing to release Patrick Ada on a free transfer before the window closes.
The former Crewe man only signed a two-year deal at Rugby Park over the summer and he has impressed during his short time at the club.
However, tight financial restrictions mean Kilmarnock are now trying to reduce their wage bill and manager Kenny Shiels is willing to part company with Ada.
The Cameroon defender is unlikely to be short of suitors having made a positive impression in the Scottish Premier League.
Ada, who has started three SPL games this season, made 42 appearances for Crewe in League Two during the 2010/11 campaign.
