The L.A. County Sheriff's Department said that police responded to a single-vehicle rollover crash around 7:12 a.m. PT on the border of Rolling Hills Estates and Rancho Palos Verdes. The vehicle, which Woods was driving alone, sustained major damage, according to the report.
The statement also said Woods was "extricated from the wreck with the 'jaws of life' by Los Angeles County firefighters and paramedics." He was taken to the hospital by ambulance.
In a statement to Golf Digest's Daniel Rapaport, Woods's agent Mark Steinberg said the golfer is undergoing surgery.
"Tiger Woods was in a single-car accident this morning in California where he suffered multiple leg injuries," Steinberg said. "He is currently in surgery and we thank you for your privacy and support."
