Jaguars sign Harrington off Cards' practice squad

The Jacksonville Jaguars have signed first-year defensive end Chris Harrington off Arizona's practice squad and waived first-year defensive back Kennard Cox.

The moves on Friday came as the Jaguars continued to look for help along a defensive line that has suffered season-ending injuries to Reggie Hayward, Rob Meier and Bryan Smith. The team also waived defensive tackle Derek Landri last week.

The Cardinals drafted the 6-foot-5, 260-pound Harrington in the sixth round in 2008. He spent time on Arizona's practice squad last season before getting signed by Cincinnati and playing three games. The Bengals waived Harrington during final cuts in September and he rejoined Arizona.

Cox played in three games this season and spent nine weeks on the practice squad.
