The head coaches of the Seattle Seahawks and Denver Broncos insist the wintry New Jersey conditions will not be the deciding factor in Super Bowl XLVIII.

As expected, much of the build-up so far has surrounded the likelihood of freezing conditions in MetLife Stadium on Sunday.

With this Super Bowl being the first played outside in a cold-weather city, it presents challenges for both the NFL themselves and teams, not just on Sunday but throughout the week as their practices are impacted.

And as if that is not difficult enough, New York itself creates added difficulties - as illustrated by Monday's Denver media activities taking place on a cruise ship.

Their coach John Fox was quick to dismiss fears upon arriving in the city on Sunday, saying: "I think in order to be a championship football team we've got to be weatherproof, and I think our football team played in all different elements this year.

"I feel comfortable with where we're at as far as the elements, but it's a part of the game.

"I think tradition-wise, it's been a part of the league and a part of a lot of championships."

Those sentiments were echoed by his opposite number Pete Carroll, who said at a press conference: "We play in an area that has inclement weather occasionally so it is not something we are bothered by.

"There are obviously some differences with the ball getting wet and the wind altering the game but, for us, it's no big deal."

Such comments will no doubt come as a relief to commissioner Roger Goodell, who has come under fire in some quarters for the decision to play a Super Bowl in such conditions.

For his part, Goodell has not been too flustered, telling British journalists at an SJA Lunch in November: "The reason we did it is that it went back to our roots.

"Part of the reason people love the Super Bowl is because it is about the elements. I think it is going to be extraordinary."
