A blizzard menacing the Eastern United States disrupted the sports schedule Friday, complicating team travel and blanketing the field where Sunday’s NFC championship game will be played with a wintry mix.

In Charlotte, North Carolina, crews scrambled to keep up with the storm, clearing snow and sleet from the tarp covering the Bank of America Stadium field. The Carolina Panthers host the Arizona Cardinals in the NFC championship game Sunday night.

Fans from afar who planned to make the trip were forced to scramble, too. Delta was among a handful of airlines that canceled all Friday flights to and from Charlotte. The forecast for the game was for clear skies, with temperatures in the mid-20s.

The NHL initially shifted the starting time of Friday’s game between the Washington Capitals and Anaheim, moving it up two hours to 5 p.m. The league then postponed it but did not yet have a makeup date.
