6 Hurt by Ice Falling off Cowboys Stadium

Hard ice and heavy snow slid off Cowboys Stadium's domed roof Friday, injuring at least six private contractors hired to prepare the venue for the Super Bowl, authorities said.

One man was struck in the head and another was hit in the shoulder, said Arlington Fire Department spokesman Pete Arevalo. They were in stable condition Friday afternoon. The other four injuries were considered minor.

Emergency personnel responded about 1 p.m. to reports of snow and ice sliding off the southern end of the sprawling stadium where the group was working, Arevalo said.

On Friday, video showed sheets of snow and ice cascading off the stadium dome.

Food service worker Doug McCracken said he and a friend pulled up to the area just in time to see what looked like snow flurries blowing off the building. Wonder turned to shock when he realized someone had been hit.

"What we saw was hard ice. It shattered, it was everywhere," McCracken said. "We thought maybe it was snow at first but it was ice. Hard ice."

The National Weather Service had issued a winter storm warning Friday for Arlington, home of the $1.3 billion stadium where the Pittsburgh Steelers and the Green Bay Packers will play this weekend for the NFL title.

The latest punch of unusual cold and snow hit a city still struggling to recover from Tuesday's ice storm, part of a massive system that paralyzed a large swath of the country with blizzards, thundersnow and bone-chilling temperatures this week. CBS News correspondent Don Teague reports that temperatures in the teens and 20s have kept many Super Bowl tourists stuck in their hotel rooms. Statewide more than 2,400 flights have been cancelled in the just the last two days, making it that much harder for fans who still have not arrived to make it to the ice-bound Super Bowl.

Forecasters expect a mostly sunny Super Bowl Sunday with highs in the 40s, and organizers had already said last week that the stadium's retractable roof would be shut for the game.

All stadium entrances, except for one truck tunnel, were closed after the ice and snow fell and authorities set up a perimeter extending about 100 feet around the area.

Arevalo said the area will remain secure until the ice on the stadium is gone. He said the NFL has raised the temperature inside in an attempt to melt the ice before it can come down.

"What we're focusing now is first the stadium and the people that were injured," NFL Commissioner Roger Goodell said. "Second is the safety of the people around the stadium ... The likelihood is they'll have to get somebody up there to get the snow off as soon as possible."
