Reportedly it’s Jemal Singleton:

Singleton was hired by Kentucky only a few weeks ago. If the NFL comes calling, then I guess you’ve gotta change your mind and make the jump.

He’s got a good track record, having been a running backs coach with the Colts, Raiders, and Bengals. Previously, he had the same job with Arkansas, Oklahoma State, and Air Force. Not sure how far back your college football knowledge goes, but he actually played at Air Force in the mid 1990s and comes from a military family. His dad was an Air Force Sergeant and Singleton was born on a U.S. air base in Turkey.

Experienced coach right here. Singleton has coached Joe Mixon, Marlon Mack, Gio Bernard, Frank Gore, Alex Collins, and Marshawn Lynch. Let’s see what he can do with this group.
