ARLINGTON, Texas (KDKA) — Falling sheets of ice and snow from Cowboys Stadium have injured six people in Arlington, Texas.

One person was hit in the head and is listed in critical condition.

KDKA’s Ross Guidotti reports this happened around 1 p.m.

The people who were hurt were apparently those working in and around the grounds trying to get it ready for the Super Bowl.

Officials have closed all but one entrance to the stadium and an 80-ft. perimeter has been established around the facility.

Southwest flights left about midday and many of the morning filling the airport bars gand

“They’ve already had, I believe, a helicopter going around identifying areas where this could be an issue,” NFL Commissioner Roger Goodell said. “The likelihood is they’ll have to get somebody up there to get the snow off as soon as possible. So they likely will be doing that in the next 24 hours.”

Gutters about 6-ft. wide surround the dome, but weren’t large enough to capture the falling ice.

The ice and snow are remnants of what’s being called the worst week of winter weather in decades.

“This is something that I’ve never seen in this area,” Duffy McKenzie said.

McKenzie’s firm is one of many tasked with removing the ice and snow on the grounds Cowboys Stadium.

Highway road graters and smaller machines moved all day back and forth trying to remove what winter dumped.

More assets are said to be on the way in a desperate attempt to save the Super Bowl from the remnants of winter’s wrath.

“We have had three tractor trailer loads of deicer delivered so far and I think a fourth is on the way,” McKenzie said.
