Scott Fox will leave Ross County after failing to agree terms on a new deal.
Fox, who was voted into the Championship team of the season, will bring an end to his four-year stay in the Highlands on the back of promotion to the top flight.
The former Scotland squad goalkeeper joined from Partick Thistle in 2015, being brought to the club by Jim McIntyre and helping the club to the League Cup final. However, after saving a penalty from Leigh Griffiths in the semi-final, injury ruled him out of the final against Hibernian and Gary Woods went between the posts.
Despite relegation last season he opted to stay at Victoria Park and was an ever-present in the league, as County secured an immediate return to the Premiership. Teenage back-up Ross Munro was preferred by management duo Stuart Kettlewell and Steven Ferguson for the IRN-BRU Cup matches, which saw them lift the trophy in March.
It now leaves the Staggies looking for immediate goalkeeping help ahead of their top-flight return, with Munro their only other senior goalkeeper in the squad at just 19.
