The NFL has decided that the Super Bowl contest between the Seattle Seahawks and the New England Patriots will be played under an open roof at the University of Phoenix Stadium.
The Phoenix is usually the home of the Arizona Cardinals, who have played each of their games at the stadium with a closed roof since December 2013.
Weather experts have predicted temperatures of around 21 degrees celsius for the league showpiece, with the heat dropping down to around 10 degrees by the end of the fourth quarter.
The Seahawks are looking to claim back-to-back Bowl crowns with victory over Bill Belichick's men.
