The Falcons hired Mark Collins to serve a defensive assistant coach on Monday.
Collins has spent 11 years coaching in the college ranks.
He coached the safeties for Louisiana-Monroe last season after serving as a graduate assistant at the University of Georgia in 2007.
Collins, a 1998 graduate of East Tennessee State, has had coaching stints at East Tennessee State, Michigan, Elon and Georgia Southern.
Collins was the defensive coordinator at Elon and worked under Falcons defensive coordinator Brian VanGorder while at Georgia Southern. He coaches the linebackers at Georgia Southern.
Collins was named as The Citadel’s defensive coordinator in February.
Collins will work closely with VanGorder, but will not be assigned a specific position group to coach.
