DENVER (AP) — Authorities say a football fan leaving the Broncos game Monday night suffered serious injuries after the person fell 30 to 50 feet at Sports Authority Field at Mile High, KDVR-TV reports (http://bit.ly/2dRuX7A).

A Denver Fire Department spokesman says the fall happened about 9:44 p.m., and emergency personnel responded to a call for help from the area of Gate 5, the Denver Post reports (http://dpo.st/2eN714g).

The spokesman did not know the distance the person fell. The person was taken to Denver Health Medical Center with serious injuries, the Post says.
