Despite hiring Ron Prince as assistant head coach, Detroit head coach Jim Caldwell is still interested in hiring David Culley as offensive coordinator. The Lions made several moves Friday on the coaching staff, including officially hiring Prince and inking Teryl Austin as defensive coordinator.

The team is adding Dwaine Board as defensive line coach and is expected to hire Ray Hamilton to also work with the defensive line, which features the talented threesome of Ndamukong Suh, Nick Fairley and Ziggy Ansah.
