Denver Broncos offensive lineman Dwayne Carswell (search) was taken to the hospital Thursday morning following a five-car accident, police said.

Broncos general manager Ted Sundquist (search) 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 (search) 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.

Carswell was in one of three cars traveling south when two northbound cars collided and veered into the southbound lanes. Several of the cars were extensively damaged, Guzman said.

"In no shape or form was [Carswell] the one that caused the accident," Guzman said.

Hospital spokeswoman Beverly Petry said Carswell was still being evaluated. She didn't know the extent of his injuries or his condition.

Carswell, 33, a former tight end for Denver, is in his 12th year in the NFL. He caught two touchdown passes against Jacksonville this year.
