Defender Mihael Kovacevic has left Ross County by mutual consent.
The club announced that they had "mutually agreed to terminate the contract" of the former Dundee United player.
The 25-year-old made 47 appearances in 18 months in Dingwall but had not featured since before Christmas.
Manager Derek Adams has brought in six players during their unbeaten January, including defenders Yann Songo'o and Evangelos Oikonomou.
A club statement read: "Mihael's departure adds to those of Grant Munro, Ivan Sproule and Orhan Mustafi who have all moved during season 2013/14, and this has given Ross County Football Club room to add to their squad over the January transfer window with great success."
