According to this Tweet from the Arizona Cardinals internal reporter, Darren Urban, the team has hired Ray Horton as the next Defensive Coordinator.

Horton leaves his job as the defensive backs coach with the Pittsburgh Steelers to reunite with his old buddy, Ken Whisenhunt. The two coached together on the Steelers staff for three years.
