LOS ANGELES (AP) — Tiger Woods was seriously injured Tuesday when his SUV crashed into a median, rolled over and ended up on its side on a steep roadway in suburban Los Angeles known for wrecks, authorities said. The golf superstar had to be pulled out through the windshield, and his agent said he was undergoing leg surgery.

Woods was alone in the SUV when it crashed into a raised median shortly before 7:15 a.m., crossed two oncoming lanes and rolled several times, authorities said at a news conference. No other cars were involved. The 45-year-old was alert and able to communicate as firefighters pried open the front windshield to get him out.

The airbags deployed, and the inside of the car stayed basically intact and that “gave him a cushion to survive the crash,” Los Angeles County Sheriff Alex Villanueva said. Both of his legs were seriously injured, county Fire Chief Daryl Osby said.

They said there was no immediate evidence that Woods was impaired. Authorities said they checked for any odor of alcohol or other signs he was under the influence of a substance and did not find any. They did not say how fast he was driving. The crash happened on a sweeping, downhill stretch of a two-lane road through upscale Los Angeles suburbs. Sheriff’s Deputy Carlos Gonzalez, who was the first to arrive at the wreck, told reporters that he sometimes catches people topping 80 mph in the 45 mph zone and has seen fatal crashes there.

“I will say that it’s very fortunate that Mr. Woods was able to come out of this alive,” Gonzalez said. Woods was in Los Angeles over the weekend as the tournament host of the Genesis Invitational at Riviera Country Club, where he presented the trophy on Sunday. He was to spend Monday and Tuesday filming with Discovery-owned GOLFTV, with whom he has an endorsement. A tweet Monday showed Woods in a cart smiling with comedian David Spade.

Woods, a 15-time major champion who shares with Sam Snead the PGA Tour record of 82 career victories, has been recovering from Dec. 23 surgery on his lower back. It was his fifth back surgery and first since his lower spine was fused in April 2017, allowing him to stage a remarkable comeback that culminated with his fifth Masters title in 2019.

He has carried the sport since his record-setting Masters victory in 1997 when he was 21, winning at the most prolific rate in modern PGA Tour history. He is singularly responsible for TV ratings spiking, which has led to enormous increases in prize money during his career. Even at 45, he remains the biggest draw in the sport.

Crews used a crane to lift the damaged SUV out of the hillside brush. The vehicle was placed upright on the street and sheriff’s investigators inspected it and took photos. Then it was loaded onto a flatbed truck and hauled away Tuesday afternoon.
