The sky is falling in Dallas and David Buehler is lucky to be alive. Buehler was sprinting across the Dallas Cowboys’ indoor practice arena when the roof of the facility suddenly collapsed. He tried to make it out the door, but a metal pole crashed into his head causing a concussion, ripping skin off his ear and gashing his knee that would require stitches. According to Dallas Morning News, Buehler said:

“My initial thought was, how many people are dead in this?…I thought I was the lucky one.”

And Buehler was right about his luck: Special teams coach Joe DeCamillis suffered broken back, assistant athletic trainer Greg Gaither suffered a broken leg, college scouting coordinator Chris Hall’s arm was injured; and scouting assistant Rich Behm was listed in critical condition with unspecified injuries.

Authorities are still investigating the cause of the collapse.
