A Denver Broncos fan was hospitalized after falling from an escalator at Sports Authority Field at Mile High during Thursday night's preseason game between the Broncos and Arizona Cardinals, according to CBS4-TV in Denver.
Police said the fan could have serious bodily injuries because of the fall but was conscious and breathing at the time he was taken to a hospital.
The identity and age of the man was not released by police and they have not said if alcohol played a role in the incident.
The escalator was apparently later roped off by authorities.
Police are seeking witnesses who may have seen the incident.
The Cardinals beat the Broncos 32-24 in the preseason finale.
