PORTLAND, Ore. -- A pedestrian was critically injured after being hit by at least one vehicle in Southwest Portland Thursday morning.

Crews called at about 6 a.m. to the crash at Southwest 6th Avenue and Broadway found a man suffering from traumatic, potentially life-threatening injuries, according to Sgt. Pete Simpson of the Portland Police Bureau.

The man was taken to a nearby hospital.

"Preliminary information indicates that the pedestrian was struck by two different drivers, both of whom have remained at the scene," Simpson said.

Investigators believe the man was crossing Broadway in a crosswalk, but was crossing against the signal when he was hit.

The man's name has not been released.

No citations have been issued.
