The Ravens worked out cornerback Chevis Jackson on Tuesday, a sign that the team is looking to upgrade its secondary.
Jackson, a third-round pick in 2008, was released by the Atlanta Falcons after being the team's nickel back for most of the past two seasons.
He struggled covering wide receivers in space or man-to-man coverage this preseason, according to the Atlanta Journal-Constitution. A former standout at LSU, Jackson started three games for Atlanta.
His biggest play was returning an interception 95 yards for a touchdown against the New Orleans Saints during his rookie season.
The Ravens' cornerbacks are: Fabian Washington, Lardarius Webb, Josh Wilson, Chris Carr and Bryan McCann. Cary Williams is currently serving a two-game suspension.
To fill out their practice squad, the Ravens also worked out three cornerbacks (Lydell Sargeant, David Pender and Terrail Lambert) and two offensive tackles (Andrew Gardner and Jake Bender).
