Carroll was expected to sign a contract Wednesday, giving the Jaguars depth behind starters Rashean Mathis and Brian Williams and nickel back Terry Cousin. Backup cornerback Scott Starks sprained an ankle against the New York Jets on Sunday, but he wasn't expected to miss any games. The Packers waived Carroll less than 24 hours after his inconsistent performance against Philadelphia on Oct. 2.
Carroll, selected in the first round of the 2004 NFL draft by the Packers, broke up three passes and had a sack this season for Green Bay. But he also got burned for two touchdowns, was flagged for pass interference and called for holding in four games.
Jacksonville is expected to place linebacker Mike Peterson (torn pectoral muscle) on injured reserve Wednesday to make room for Carroll.
Carroll has 104 tackles, three sacks, three interceptions and 26 passes defended in 34 career games. He also has returned 21 kickoffs for 421 yards.
