Franks, 26, is a 2010 Atlanta Falcons fifth-round draft pick from Oklahoma. The 6-foot, 197-pound defensive back has 30 tackles, three interceptions and nine passes defended in four NFL seasons , including four 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.
Backup nose tackle Terrence Cody remains on the physically unable to perform list after undergoing offseason hip surgery.
