A blizzard moving into 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 there in the NFC championship game on 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 flights to and from Charlotte on Friday because of the storm. The forecast for the game was calling for clear skies, with temperatures expected to be in the mid-20s.

Two NBA games and one in the NHL were postponed, as were several college basketball games and NASCAR’s Hall of Fame induction ceremony.

The NBA said Boston’s game at Philadelphia scheduled for Saturday night will be made up on Sunday at 7 p.m. The Utah Jazz’s game at Washington, scheduled for 6:30 p.m. Saturday, will be reset at a later date.

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 on Friday but did not yet have a makeup date. A decision regarding Sunday’s game between the visiting Pittsburgh Penguins and Capitals will be announced Saturday morning.

Up to 2 feet of snow was predicted from what the National Weather Service was calling a “potentially crippling winter storm.” A state of emergency was declared in Pennsylvania for Saturday.
