Super Bowl coaches John Fox and Pete Carroll expressed concern Sunday that snow on the practice fields could hinder their preparation this week.
But the NFL said both teams will have the ability to practice outside.
The New York metropolitan area has been hit with snow and icy temperatures for several weeks. Fox's Denver Broncos will train at the Jets' facility in Florham Park. Carroll's Seattle Seahawks will work at the Giants' complex at the Meadowlands.
Fox said Sunday he prefers the natural grass field outdoors because it "saves players' legs," and the Broncos have brought along their field experts, adding "We'll see if we have to go inside or on their artificial turf."
Carroll said he "understands there's snow on the field and it's frozen and we likely could be inside most of the week."
He added he would like to get the Seahawks outside as much as possible so they can adjust to weather far different from Seattle's climate.
