Nearly four years removed from his last NFL coaching position, former Detroit Lions head coach Jim Caldwell is joining Frank Reich's staff with the Carolina Panthers as a senior defensive assistant, according to multiple reports.
Caldwell, who posted a 36-28 record in four seasons with the Lions, briefly served as quarterbacks coach and assistant head coach for Brian Flores in Miami during the 2019 offseason, prior to stepping away from the position to address a personal health issue.
During the past two offseasons, Caldwell has interviewed for multiple head-coaching vacancies, including the Panthers job that ultimately went to Reich.
