ARLINGTON – A piece of metal and small debris fell onto the field while AT&T Stadium's retractable roof was being opened Monday before the Cowboys-Texans game.No injuries were reported, according to the Cowboys.

A massive piece of sheet metal fell from the roof of AT&T stadium while it was retracting to open for Monday night’s Cowboys game. According to NBCDFW, the Cowboys had hoped to be playing tonight’s game against the Texans with the roof open for the first time in two years.

Before the game, the domed roof at AT&T Stadium could be seen being opened, something that hasn't happened for a Cowboys game in over two years. Unfortunately, plans to play the game under the night sky in Arlington were foiled after a metal sheet fell off the roof, forcing the stadium to close the dome back up.
