The man fell on another fan seated in the mezzanine area during the game Friday evening, The Georgia World Congress Center Authority, which operates the downtown football stadium, said in a statement.
Investigator Leon Harrison at the Fulton County Medical Examiner's Office told The Associated Press early Saturday that Isaac Grubb of Lenoir City, Tenn., was pronounced dead Friday night, minutes before midnight, at an Atlanta hospital.
He said the man had fallen about 35 feet and appeared to have suffered injuries from blunt force trauma.
Jennifer LeMaster, a spokeswoman for the Georgia World Congress Center Authority, told AP before the death was confirmed by Harrison that she had no information beyond the authority's initial statement. She said, however, the authority was expected to release more information Saturday afternoon.
The authority had said the fall occurred about 8:30 p.m. Friday night during the game in which Tennessee beat North Carolina 35-21.
