The St. Louis Rams added another free agent this week. Former Saints linebacker Jo-Lonn Dunbar is the latest addition to the team's depth chart. Dunbar revealed the news on Monday morning via Twitter.

Dunbar had been on the team's radar previously in free agency. St. Louis is looking to replace both its starting outside linebackers from last season, Chris Chamberlain and Brady Poppinga, who left via free agency this year. Chamberlain landed in New Orleans, reunited with Steve Spagnuolo. Poppinga has yet to sign with another team.

Dunbar was the Saints' lowest graded linebacker last season, getting a -26.3 mark from Pro Football Focus. He played all three linebacker spots, getting most of his work on the strongside. Hopefully last season was an anomaly for him. In 2010, with far fewer snaps, he graded out as a 5.0. He was mostly a backup and special teams contributor with the Saints, until last season.

The question for the Rams now is whether or not Dunbar's name comes up as the league moves to punish players involved in Bounty Gate. He seems likely to compete for one of the outside linebacker spots and have a role on special teams.

New Orleans signed Dunbar, a Boston College product, as an undrafted rookie free agent in 2008.
