The Detroit Lions have filled one of their open coordinator positions, elevating linebackers coach Kelvin Sheppard to defensive coordinator, NFL Media reported on Saturday.

Sheppard, 37, takes over for Aaron Glenn, who left to become the head coach of the New York Jets on Wednesday following the Lions’ divisional-round playoff loss to the Washington Commanders last weekend.

When Glenn took over as Detroit’s DC in 2021, Sheppard came on board and has spent the last four seasons learning under the former three-time Pro Bowl defensive back and 15-year NFL veteran.

Sheppard, who played linebacker for eight NFL seasons, including his final season with Detroit in 2018, served as director of player development at LSU — where he played college football — in 2020 before returning to the Motor City.

Detroit remains in search of an offensive coordinator to replace Ben Johnson, who took over head coaching duties with the Chicago Bears on Tuesday.
