According to NFL Network's Ian Rapoport and Mike Garofolo, the team is promoting LBs coach Kelvin Sheppard to defensive coordinator. He'll take over for new New York Jets head coach Aaron Glenn.

The Detroit Lions have gone through a brain drain within the coaching staff in the aftermath of their season-ending loss to the Washington Commanders in the divisional round. Since that defeat, Ben Johnson has been hired as the head coach of the Chicago Bears and Aaron Glenn has inked a deal to lead the New York Jets,

Detroit's defensive coordinator was previously Glenn, who had held down the fort at this spot since 2021. Glenn left to take the New York Jets head coach opening, and it was a return to his roots, as Glenn spent eight seasons of his playing career with the Jets.
