Rashean Mathis

The 35-year old has made 137 career appearances with the club and is the Jaguars' franchise leader in interceptions. He was with the team from 2003 to 2012, before spending three seasons with the Lions.

Mathis finished this past season on injured reserve after dealing with concussion/brain issues and was expected to retire. The 2006 All-Pro played 13 productive seasons in the NFL, the last three of which in a Lions' uniform.

The 13-year career of Rashean Mathis has been on that appears to go under-rated. He has always been one of the better cover corners in the league. He spent the first 10 years of his career in Jacksonville, being named to the First-Team All Pro in 2006. The next three years were with Detroit where his numbers were on the decline. Throughout his career, Mathis had 32 interceptions, eight forced fumbles, and 187 passes defended. The Lions will need to find help in the secondary over the course of the off-season.

Mathis has suffered a few concussions in his time in the NFL and this last one has him doubting if he will ever be able to step onto the field again. He was cleared with a clean bill of health but at this point, Mathis is thinking about his future and not just the present. He will take the offseason to really think things through, but retirement is a definite possibility at this point.
