Denver Broncos offensive lineman Dwayne Carswell was taken to the hospital Thursday morning following a five-car accident, police said. Broncos general manager Ted Sundquist told KCNC-TV in Denver that Carswell tore his diaphragm and had internal bleeding in his chest. Doctors were trying to determine whether there were injuries to his heart or aorta, Sundquist said. Team spokesman Jim Saccomano said Carswell was undergoing surgery but refused to release any details. Officer Tony Guzman didn't know the extent of Carswell's injuries. A woman also was taken to the hospital. Her name was not released.
