Ravens promote Toussaint to roster

The Baltimore Ravens promoted running back Fitz Toussaint from their practice squad after releasing cornerback Derek Cox.

Toussaint is the third undrafted rookie on the Ravens' season-opening 53-man roster, joining linebacker Zachary Orr and offensive tackle James Hurst.

Touissant flashed his explosiveness in the preseason finale with several big runs. Toussaint ran for 103 yards at New Orleans, averaging 6.1 yards per carry.

The Ravens have four tailbacks on their roster with Bernard Pierce, Lorenzo Taliaferro, Justin Forsett and Toussaint. Pierce is expected to replace suspended Ray Rice as the the Ravens' starting running back for the first two games of the season.
