Among a group of cornerbacks trying out for roster spots that also included Drayton Florence, Marquice Cole, Bobby Felder and Kevin Thomas, Ross and Franks made the most plays over the past three days.
The Ravens also have agreed to terms with linebackers Austin Spitler and Nick DiMarco.
A former first-round draft pick out of Texas, Ross, 31, won a pair of Super Bowl championships with the New York Giants. He played for Ravens secondary coach Steve Spagnuolo as a rookie for the Giants when they won Super Bowl XLII in 2008.
Ross is a 6-foot-1, 193-pound veteran who has played in the NFL for seven seasons. His season last year was cut short by a back injury, and the Giants placed him on injured reserve. Ross emphasized this week that he has made a complete recovery from the back injury.
Ross has 11 career interceptions and 41 passes defended.
Franks is a 2010 Atlanta Falcons fifth-round draft pick from Oklahoma.
The 6-foot, 197-pound Franks, 26, has 30 tackles, three interceptions and nine passes defended in four NFL seasons with four career starts.
Franks played in 15 games last season as a reserve cornerback for Atlanta. The Falcons released him during their final major roster cutdown before re-signing him after he worked out for the Kansas City Chiefs, Miami Dolphins and Pittsburgh Steelers.Copyright © 2015, The Baltimore Sun
