Four Dallas Cowboys staff members were injured Saturday when the roof of the team's indoor practice facility collapsed.
Cowboys spokesman Rich Dalrymple said all players and coaches were accounted for, and he didn't know the extent of the injuries to the four staff members, who were hospitalized.
Rescue personnel were still going through the debris to make sure everyone was accounted for, Dalrymple said.
Irving fire-rescue officials ordered all reporters and team personnel away from the immediate area.
The roof is a large air-supported canopy with aluminum frames covering a regulation 100-yard football field.
Power was out at the Valley Ranch facility.
