Jon Hoke, the Bears' defensive backs coach for the past four years, will remain with the team in the same capacity under new head coach Marc Trestman.
Gill Byrd, who assisted Hoke as the Bears' assistant defensive backs coach/safeties the past five years, will not return after seven years on Lovie Smith's staff. Byrd joins offensive coordinator Mike Tice, linebackers coach Bob Babich, quarterbacks coach Jeremy Bates, tight ends coach Mike DeBord, wide receivers coach Darryl Drake, offensive line coach Tim Holt and running backs Tim Spencer, who also were not retained.
Babich has already been hired as the Jacksonville Jaguars' defensive coordinator, replacing Mel Tucker, who was hired by the Bears for that job on Friday.
Trestman wanted defensive coordinator Rod Marinelli to remain on his staff, but Marinelli left to coach the Cowboys' defensive line under their new defensive coordinator Monte Kiffin. Marinelli and Kiffin worked together for 10 years with the Tampa Bay Buccaneers.
Trestman still must hire coaches for linebackers and wide receivers plus other assistant position coaches.
