GLENDALE, Ariz. (AP) — Authorities say the roof of the Arizona Cardinals' stadium in Glendale was slightly damaged Thursday by a thunderstorm that packed high winds.
Video from TV news helicopters show several tears in one section of the white, canvas-like fabric that stretches across the roof's steel girders.
University of Phoenix Stadium spokesman Scott Norton says it's possible that wind gusts got under the metal skin of the structure, flipping a piece of it up and onto the roof and causing the fabric puncture.
Norton says water and debris such as insulation fell onto the stadium floor. He says there are no reported injuries and all employees inside the stadium have been safely evacuated.
Norton says stadium officials are evaluating the extent of the damage and how much it will cost to repair it.
The Cardinals report to training camp Friday in Flagstaff. They open their preseason schedule at home Aug. 14 against Houston.
