The Tennessee Titans are keeping their assistant offensive line coach in the fold.

A source told Sporting News that Mike Sullivan will be returning to the team and working under new offensive line coach Keith Carter.

Sullivan has coached in the NFL for 15 of the past 17 years, including the last four with the Titans.

Sullivan previously had two stints as Cleveland’s offensive line coach (2007-08 and 2013) and did the same with San Diego from 2009-12.
