The Jets yesterday signed free-agent defensive back Ahmad Carroll and waived defensive back Nate Lyles.

Carroll, 5-10, 190 pounds, spent the 2008 season with the Arena Football League’s Orlando Predators, starting 15 of 16 games with 68 total tackles (60 solo), three fumble recoveries and an interception.

He originally was selected by the Packers in the first round of the 2004 NFL Draft. In 2006, Carroll was waived by the Packers and signed as a free agent with Jacksonville, where he played in one game before being waived.

Lyles signed as an undrafted rookie free agent on May 2, was a three-year starter at cornerback for Virginia.
