Field Yates of ESPN reports that the Lions are hiring Eagles defensive backs coach Cory Undlin as their new defensive coordinator.
Yates notes that Undlin and Lions HC Matt Patricia both began their NFL careers together as coaching assistants with the Patriots in 2004.
The Lions made the decision to move on from Paul Pasqualoni after the season. They were linked to Bret Bielema, but that report was later shot down.
Undlin, 48, began his coaching career as the linebackers coach at California Lutheran. He took his first NFL coaching job in 2004 a defensive coaching assistant for the Patriots.
From there, Undlin worked for the Browns, Jaguars and Broncos before the Eagles hired him as their DBs coach in 2015.
