DALLAS (Reuters) - Seven people were injured on Friday by falling ice at Cowboys Stadium, the venue for this year's Super Bowl, and all entrances to the venue have been closed except for one, the NFL said.
"The ice and snow melting off of the Cowboys Stadium roof has caused several sliding snow falls onto the plazas. A total of seven people were injured," said NFL spokesman Brian McCarthy.
McCarthy added that all seven people went to hospital for attention -- five of them in their own cars.
"We are continuing to evaluate snow on the roof.
"All stadium entrances have been closed except for the truck tunnel, which is away from the building by a very safe distance. All workers and visitors will now enter and exit through the tunnel until further notice".
Local media said sheets of ice and snow slid off the domed roof of the stadium and plunged to the ground as temperatures warmed up after four days of freezing conditions.
