MINNEAPOLIS  The roof of the Metrodome deflated early Sunday morning under the weight of the heaviest snowfall in almost two decades, forcing the N.F.L. to move the game scheduled to be played there between the Minnesota Vikings and the Giants to another domed stadium in Detroit on Monday night.

The decision set off a multicity scramble. The Giants, who had been stranded in Kansas City, Mo., on Saturday night after their flight to Minneapolis was diverted because of the storm, hastily made plans to fly to Detroit. The Vikings did the same.

“It’s like recreating a bad Christmas movie,” Giants defensive lineman Justin Tuck said.

Things were hectic at Detroit’s Ford Field as well, where minutes after the Lions concluded a 7-3 victory over the Green Bay Packers, workers began scrubbing Lions logos from the end zones to paint in those of the Vikings, part of an attempt to give the field the look of a home game for them.

“We’re going to work to make this as accommodating of a game for both teams, but particularly the Vikings, since it is their home game that is being lost,” Tom Lewand, the Lions’ president, said.
