ALLEN PARK, Mich. (AP) -- The Detroit Lions have hired Cory Undlin to replace Paul Pasqualoni as defensive coordinator.
The Lions announced earlier this month Pasqualoni was leaving the team to be closer to his family in Connecticut.
Undlin's task is to turn around a defense that ranked No. 31 in the NFL for a team with three wins in 2019. He was Philadelphia's defensive backs coach for five seasons after having the same job for two years during a three-season stretch with the Denver Broncos.
Patricia has made several changes on his coaching staff after hanging onto his job for a third season despite his 9-22-1 record.
He fired six members of his staff two days after finishing the season 3-12-1. Later, Patricia said Pasqualoni was leaving for family reasons and offensive line coach Jeff Davidson was taking an indefinite leave from the profession.
Patricia filled a key role on Saturday, hiring special teams coordinator Brayden Coombs. He previously promoted assistant coaches Hank Fraley and Billy Yates to lead the team's offensive line.
Patricia and his new-look staff will have an opportunity at the Senior Bowl to evaluate draft prospects later this month as coaches for practices and the game. The Lions have the No. 3 draft pick overall in April.
