Chesterfield manager Lee Richardson has completed the signing of Kevin Gray. The 35-year-old has ended a three-and-a-half year spell at Carlisle and has also played for Tranmere, Stockport, Huddersfield and Mansfield.
"I am delighted Kevin, an ex-team-mate of mine, is joining us as he is a great character to have around," Richardson told the club's website.
"He will bring a wealth of experience to the squad to help us achieve promotion," he added.
