NFL commissioner Roger Goodell has refused to commit to the Super Bowl returning to a cold-weather location after this season.

This year's event will take place in New Jersey next month, opening the possibilities to the likes of Philadelphia and Buffalo being awarded the showpiece match in the future.

However, Goodell stressed that having the city of New York was a major factor in the decision and would not say whether other cold-weather sites would be awarded the event in the near future.

"I think this is obviously innovative and it's something new, but it's also unique because it's New York," Goodell told former Associated Press correspondent Ben Feller.

"This is a stage, we have two teams here. Every city can't host a Super Bowl just because of the sheer enormity of this event. And it's not just a football game.

"We have a week full of events, we probably have well over 150,000 coming in to the New York region for this event. Will we look at other Super Bowls in cold-weather sites? I think we'll wait and make that evaluation later."

Next year's Super Bowl will take place in the warmer conditions of Arizona.
