Former Lions defensive coordinator Cory Undlin heading to the 49ers as DBs coach

Undlin’s defense finished dead last in his one year in Detroit

Former Detroit Lions defensive coordinator Cory Undlin has found a new job. Undlin will join the San Francisco 49ers as the pass game specialist/secondary coach under new defensive coordinator, Demeco Ryans.

Undlin ran the Lions defense under Matt Patricia in the 2020 season. To say it did not go well for Undlin and the Detroit defense is an understatement; the Lions allowed more points and yards than any other NFL team last year, Undlin’s first and only with the team. Much of the blame does generally fall upon Patricia, but Undlin didn’t do much to help his case after the team fired the head coach with five games remaining.

Undlin coached in Philadelphia while Ryans was a linebacker for the Eagles. San Francisco continues to remake its defensive coaching staff after former coordinator Robert Saleh left to become the head coach of the New York Jets.
