Representatives from Birdair, the company that handles the fabric of the roof on the Metrodome, checked out the damage Monday evening but weren't able to pinpoint a timetable, Sports Facilities Commission chair Roy Terwilliger said.

Terwillger had been hopeful that information would have been nailed down Monday night but Birdair is awaiting additional crews to arrive to help assess the situation.

"They're set up to go to work tomorrow," Terwilliger said. "But they won't advise us until 6 tomorrow evening."

Terwilliger said an overlap with the University of Minnesota may be necessary, but he noted that's ultimately the Vikings and the NFL's call.

University officials had said they needed four days to get TCF Bank Stadium ready to host the Vikings-Bears game next Monday night.

"It's been a long day," Terwilliger said. "But, I was hopeful they would be able to tell us right away, they had no problem. But they couldn't."

After the collapse of the Metrodome roof, the Vikings home game against the New York Giants was moved to tonight at Ford Field in Detroit. The Vikings lost the game 21-3 to move to 5-8, virtually ensuring they will not defend their NFC North crown. The Vikings are not mathematically eliminated, but they would essentially need several teams to not win another game in order to even have a chance to reach the postseason.
