ATLANTA, Ga. -

A UT fan is dead after falling during a football game Friday night at the Georgia Dome in Atlanta.

20-year-old Isaac Grubb of Lenoir City, Tennessee died after falling about 35-feet from the Georgia Dome's upper level.

We're told Grubb fell onto another fan in a lower level.

Both men were taken to a hospital, where Grubb later died.

The other man was treated and released.

The medical examiner's office said Grubb suffered blunt force trauma injuries.

Officials believe the 20-year-old was drinking alcohol before he fell to his death.
