A fan reportedly fell Saturday from the upper level at Jack Trice Stadium during an Iowa State home game against Oklahoma State.
While details about the accident are limited, the Cedar Rapids ABC affiliate reported that two people were able to help the unidentified man after he fell between a guard rail and a back row of bleachers.
"He was unconscious, he was unresponsive when we pulled him out, his eyes rolled back into his head," Tom Doyle who helped the man, told ABC. "Asking him questions like who's the president, what year is it, where are we and he knew those."
The injured man apparently told Doyle that he felt pain in his left leg when he woke up.
The Des Moines Register estimated that the man fell about 25 feet from the upper deck.
Investigators have not released the man’s name or an update on his condition. This is believed to be the first incident like this since Jack Trice Stadium opened in 1975.
