They are running backs coach/run game coordinator Justin Outten, cornerbacks coach/defensive pass game coordinator Chris Harris, and defensive quality control coach Lori Locust, according to a tweet from Paul Kuharsky. Kuharksy isn't reporting that these coaches are definitely staying, but Callahan would be wise to keep all three coaches on staff.

Brian Callahan's #Titans staff so far:

Defensive coordinator Dennard Wilson

Defensive backs Steve Jackson

Inside linebackers Frank Bush
