ARLINGTON, Texas — Emergency crews atop Cowboys Stadium this morning rescued two workers who fell from a roof area while doing maintenance. The extent of the workers' injuries wasn't immediately known.

Arlington Assistant Fire Chief Don Crowson says the two were working on the top hatch of the retractable-roof venue around 7:20 a.m. Thursday when they apparently slipped.

Police spokeswoman Tiara Ellis Richard says the workers fell from an upper roof to a lower section.

Live TV coverage showed fire department crews on the roof of the nearly $1.2 billion stadium, where the NFL's Dallas Cowboys began playing this season. Crews used baskets, lines and ladders to lower the workers.

Cowboys spokesman Rich Dalrymple says the workers were on the roof for ongoing maintenance.

He did not know the extent of the injuries or if cold weather was a factor in their fall.
