ATLANTA (AP) - Authorities say a 20-year-old man who plunged about 35 feet from the Georgia Dome's upper level and struck another fan during the Tennessee-North Carolina State game has died.

The man fell on another football fan seated in the mezzanine area 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 just before midnight at an Atlanta hospital. He says an autopsy is planned and Grubb apparently suffered blunt force trauma injuries.

He says the other man was treated at a hospital and released.

Authority spokeswoman Jennifer LeMaster said it planned to release more information Saturday afternoon.
