The Detroit Lions are promoting linebackers coach Kelvin Sheppard to defensive coordinator, replacing Aaron Glenn, who left to become 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.

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,

The Lions lost offensive coordinator Ben Johnson, now head coach of the Chicago Bears, and defensive coordinator Aaron Glenn, the next New York Jets coach, and will spend the first part of the 2025 offseason looking for replacements.

The Detroit Lions will have to find a new voice to lead their defense. With Aaron Glenn off to coach the New York Jets, Dan Campbell will be tasked with finding a new defensive coordinator for the first time in his tenure.

With Aaron Glenn and Ben Johnson gone, we’re tracking all of the shifting parts of the Detroit Lions’ 2025 coaching staff.

Another Lions assistant coach is apparently heading to join Ben Johnson's new staff with the Chicago Bears. The latest to jump ship from Detroit is assistant QB coach JT Barrett. While nothing official had been announced,

Ben Johnson is taking another Detroit Lions coach with him to the Chicago Bears. According to his updated Instagram account, Lions assistant quarterbacks coach J.T. Barrett is taking a job as the new Bears quarterback coach.

The raiding of the Detroit Lions coaching staff looks like it is going to continue. According to a report from ESPN's Adam Schefter on Friday evening, the Chicago Bears are set to hire Antwaan Randle El to be their new assistant head coach and wide receivers coach.
