The Detroit Lions have hired Southern California's Brandon Sosna as the team's senior director of football administration, according to ESPN's Pete Thamel.
Sosna previously served as the chief of staff for athletics for USC and oversaw the football operations.
According to Thamel, Sosna informed his USC co-workers of his decision earlier this week.
USC athletic director Mike Bohn credited Sosna, hired as senior associate athletic director and chief of staff in December 2019, of playing a pivotal role in USC's hiring of Lincoln Riley.
Riley was named the Trojans' head coach in November after spending five seasons at Oklahoma, where he produced two Heisman Trophy winners, won five Big 12 conference championships and led the Sooners to three College Football Playoff appearances.
