Hall will join recently hired David Blackwell in the co-coordinator spot. It wasn’t immediately certain if he willcoach safeties or linebackers.
Hall couldn’t be reached immediately for comment. Grass was in a staff meeting and not available immediately.
Hall was linebackers coach at Arkansas State before joining Auburn’s staff this past season. He also was a linebackers coach at Northern Iowa and twice was a defensive quality control specialist at Oklahoma.
Grass has one more slot to fill before completing his staff -- cornerbacks and special teams coach.
