The Tennessee Titans have fired four assistant coaches, including offensive coordinator Todd Downing.

Downing had been the OC for the past two seasons.

Tennessee also fired offensive line coach Keith Carter, secondary coach Anthony Midget and offensive skills assistant Erik Frazier.

"I want to thank Todd, Keith, Anthony and Erik for their service and commitment to our team over their time here in Tennessee," Mike Vrabel said. "Each of them made an impact on our organization, were dedicated to the process and loyal members of our coaching staff."
