A man who fell 60 feet from a railing Monday night during a Denver Broncos game at the city's Sports Authority Field at Mile High has died, police said Tuesday.

Jason Coy, 36, died of blunt-force trauma, according to a report from the Denver Medical Examiner's Office obtained by The Denver Post.

Police are investigating Coy's death as a non-traffic accident, in line with standard procedure in similar cases. Investigators believe that Coy was sitting on a railing when he lost his balance and fell into a stairwell.

A Denver Fire Department spokesman told The Post that Coy fell around 9:45 p.m., after the game against the Houston Texans ended.

Witnesses and emergency personnel responded after Coy fell, according to police, and he was taken to a local hospital with serious injuries. He was later pronounced dead.

The Broncos offered condolences to Coy's family in a statement released Tuesday.

"The Denver Broncos are extremely saddened to learn that Jason Coy, the fan who fell over a stairwell railing at Monday night's game, has passed away," the statement said. "Along with Stadium Management Co., we extend our deepest sympathies and condolences to his family and friends.

"Providing a safe, enjoyable environment for guests at Sports Authority Field at Mile High is the top priority for the Broncos and SMC. We're reviewing this tragic incident and will continue to maintain all necessary safety measures for our fans."

Police are investigating to determine what led to the fall.
