DENVER (AP) — Denver Police say a man was transported to a hospital with serious injuries after falling over a railing at the start of the Denver Broncos game Sunday.

The man, who wasn’t identified, fell about 15 or 16 feet in the west stands in what appeared to be an accident. The Denver Police said he was in critical condition, but did not disclose the nature of the injuries.

Late last month, a baseball fan in Atlanta died after falling from the upper deck at Turner Field in a game between the Braves and New York Yankees.
