Chris will join Sale Sharks next season from his current club Glasgow Warriors.
Chris started his professional career with Border Reivers in 2003 and then moved to Perpignan in 2007 before joining Glasgow in 2009.
Capped 66 times by Scotland (first being against Wales in 2004), Chris also toured with the 2005 British & Irish Lions, gaining one cap.
Director of Rugby Steve Diamond said, "Chris is a great signing for the club. We have signed him to replace Dwayne Peel who is leaving us after six years at the club and we know that Chris will be the quality replacement we need. A lot of credit for the signing must go to Bryan Redpath who knows Chris well. Chris will join us in the close season and we look forward to him arriving."
