ATLANTA (AP) - Investigators say a 20-year-old Tennessee man had been drinking before he died in a fall at the Georgia Dome.

Police Lt. Chad Hurston said Saturday that authorities need to review results from the medical examiner's office to determine how much of a role alcohol played in the accident.

Isaac Grubb fell about 45 feet inside the Dome while celebrating a Tennessee touchdown against North Carolina State during a Friday night game. He struck and injured a 34-year-old man from Fort Mill, S.C., who suffered minor injuries.

Hurston said that Grubb had started drinking around 5 p.m. before he entered the Georgia Dome. He said witness reports do not indicate that Grubb bought alcohol inside the stadium.
