A bus carrying Dallas Cowboys staffers but no players and a van collided Sunday on an Arizona highway, killing four people in the van, authorities said.
The bus occupants emerged uninjured from the crash, Arizona Department of Public Safety spokesman Quentin Mehr said.
"All on the bus came through OK with some bumps and bruises," Cowboys spokesman Rich Dalrymple (DAHL'-rimp-ul) said in an email.
Dalrymple said the bus was only carrying members of the franchise's staff but would not say how many. There were no players on board.
