Actor Jason Priestley, on the fast track to a major professional racing career, was in serious condition with a concussion, broken back and other injuries from a head-on crash in his race car at almost 180 mph.
The former "Beverly Hills 90210" television star, competing in the new Infiniti Pro Series, spun into the wall at Kentucky Speedway during practice Sunday.
He was scheduled to undergo further tests, Indy Racing League medical director Henry Bock said.
"He is certainly breathing on his own," Bock said Sunday night. "His condition has stabilized. His vital signs have been stable since he left here."
Priestley was flown to the University of Kentucky Medical Center with a spinal fracture in the middle of his back and a closed head injury, as well as a broken nose and broken bones in both feet.
