PHILADELPHIA — Are you ready for some Tuesday Night Football?

The NFL moved the Vikings at Eagles game from Sunday night to Tuesday because of an expected blizzard that could dump more than a foot of snow on Philadelphia.

The game will be played at 8 p.m. EST., and televised nationally by NBC.

Philadelphia Mayor Michael Nutter declared a snow emergency as of 2 p.m. EST Sunday.

"We are urging all Philadelphians, please be careful, please be safe," the mayor told reporters in a news conference at City Hall on Sunday morning.

The decision to postpone the game came shortly after noon — before there was any snow accumulation in Philadelphia.

In announcing the postponement, NFL spokesman Greg Aiello said:

"Due to public safety concerns in light of today’s snow emergency in Philadelphia, tonight’s Vikings-Eagles game has been postponed. Because of the uncertainty of the extent of tonight’s storm and its aftermath, the game will be played on Tuesday night at 8 p.m. This will allow sufficient time to ensure that roads, parking lots and the stadium are fully cleared. The National Weather Service states that a winter storm warning in Philadelphia remains in effect until 1 pm on Monday."

The Vikings already have had two home games affected by the weather this season. Their game against the Giants on Dec. 12 was postponed a day after Minneapolis got 15 inches of snow. It was then moved to Detroit when the Metrodome roof collapsed.

Their game against Chicago the following week was played at the University of Minnesota’s outdoor stadium because of the damaged roof.

"What else can you say? Just add this to the list for the 2010 season," Vikings defensive end Jared Allen said. "But you know what, we have to remain together as a team and keep a positive mind frame. It’s important to be a professional and be ready to play on Tuesday night."

Minnesota (5-9) is out of playoff contention, but the Eagles (10-4) can clinch the NFC East with a win or if the Giants lose at Green Bay on Sunday afternoon.

"We have every reason, because of the season, to say, ‘This is the last straw and I’m checking out,’" Vikings interim coach Leslie Frazier said. "But this is the NFL and you can’t do that. You have to show up ready to play Tuesday night and that’s what we’re trying to get the young guys and everybody to understand."

NBC was uncertain what it would broadcast Sunday night in place of the game, although a spokesman said the regular "Football Night in America" would be on the air from 7 p.m.-8:30 p.m. EST.

The Eagles left their hotel, went to their practice facility for workouts and film study and then went home. They’ll now have just four days off before playing Dallas (5-10) next Sunday in a game that could determine whether they get a first-round bye.

It’s unknown what the teams will do Monday.

There won’t be any conflicts with the Flyers or 76ers because both teams are on the road. However, a Disney on Ice show Tuesday night at the Wells Fargo Center was canceled.
