JERSEY CITY, N.J. (AP) — Super Bowl coaches John Fox and Pete Carroll have expressed concern that snow on the practice fields could hinder their preparation this week.

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 says 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 says he “understands there’s snow on the field and it’s frozen and we likely could be inside most of the week.”

He adds he would like to get the Seahawks outside as much as possible so they can adjust to weather far different from Seattle’s climate.
