The Ravens are re-signing veteran cornerback Dominique Franks, according to a source.
The Ravens need depth at the position with Asa Jackson sidelined for several weeks with a severely sprained toe injury. Jackson could be out for six to eight weeks, according to a source.
Jackson remains on the roster at this time, but coach John Harbaugh said the team is considering whether to place him on the short-term injured reserve. If the Ravens do that, Jackson will miss at least eight games.
Franks was released by the Ravens in the final major roster cutdown before the season.
Franks was on his way to try out for the Detroit Lions, who are working out cornerbacks Curtis Marsh and Ellis Lankster today, when the Ravens called. Franks arrived in Baltimore on Monday night.
Franks was originailly signed by the Ravens in June following a minicamp tryout. He hasn't been with a team since being released, but did try out for the Tennessee Titans in September.
When Franks was with the Atlanta Falcons the past four seasons, he lined up inside and outside as a cornerback and nickel back.
The former second-team All-Big 12 selection from Oklahoma also played a handful of games at safety and has good size for a cornerback, at 6 feet, 197 pounds.
Drafted by the Falcons in the fifth round in 2010, Franks, 26, has 30 career tackles, three interceptions and nine passes defended in four NFL seasons with four career starts.
Franks played in all but one game as a reserve cornerback last season for the Falcons.
