IRVING, Texas -- Dallas Cowboys special teams coach Joe DeCamillis was among at least five people injured Saturday when the roof of the team's practice facility collapsed during a storm.
Cowboys spokesman Rich Dalrymple said four team support staff members were injured and all players and coaches were accounted for. He didn't know the extent of the injuries of the four, who he said were hospitalized.
Assistant coach Brett Maxie suffered a laceration on his leg, a source told ESPN.com's Matt Mosley.
DeCamillis was seen putting on a neck brace and being taken out of the team's main office building on a stretcher.
The roof came down at about 4:30 p.m. ET during a severe thunderstorm while the team was going through the second day of a three-day rookie minicamp. Cowboys owner Jerry Jones, in a TV interview from the Kentucky Derby, said 27 rookies were going through the workout.
Witnesses said lights started flickering and shaking minutes before the collapse, prompting players, coaches, staff members and reporters to vacate the building. Several people were trying to exit the facility as the roof came down.
According to the Fort World Star-Telegram, a portable toilet was blown over outside the facility and blocked an exit.
The storm was producing winds measured at 64 mph just before it struck the Cowboys facility, said National Weather Service meteorologist Joe Harris in Fort Worth.
A witness on the scene told Mosley that players and coaches raced back into the facility to try and locate people that may have been trapped.
Dalrymple said rescue personnel were still going through the debris to make sure everyone was accounted for.
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.
