High Quality Content by WIKIPEDIA articles! University of Phoenix Stadium is a multipurpose football stadium located in Glendale, Arizona. It is the home of the Arizona Cardinals of the National Football League (NFL) and the annual Fiesta Bowl. The stadium is located next door to the Jobing.com Arena, where the NHL's Phoenix Coyotes play, and it has the first fully retractable natural grass playing surface built in the United States. An opening on one side of the stadium allows the playing field to move to the exterior of the building, allowing the entire natural turf playing surface to be exposed to daylight when it is not in use and also allowing the floor to be used for other purposes without damaging the playing surface.
