Arlington Fire Department spokesman Lee Tovar says the fan was taken to a hospital after the incident Saturday night at the $1.2 billion home of the Dallas Cowboys.
Tovar says the cause of the fall and the man's condition were unknown. He estimated the fall at 12 feet to 15 feet.
Tovar would not identify the man, who was seen wearing a Texas shirt while being treated before he was taken off the field on a stretcher.
The floors of the field-level suites are a few feet lower than the field.
