Longtime Jaguars starting CB Rashean Mathis will visit the Lions on Saturday. Could upgrade and help their secondary.

Mathis, who turns 33 later this month, spent a decade in Jacksonville as one of the Jaguars’ mainstays on defense, picking off 30 passes.
However, the Jaguars elected not to bring him back as they rebuild under new coach Gus Bradley and general manager Dave Caldwell.
