Former FedEx Cup champion Bill Haas was injured in a multi-car crash on Tuesday near Los Angeles.
Haas was a passenger in a Ferrari driven by an unidentified man. Los Angeles fire officials said the driver of the Ferrari was pronounced dead at the scene, while Haas and the 50-year-old woman driving the other car were taken to hospital.
Police said actor Luke Wilson was also involved in the crash when his SUV was sideswiped by the Ferrari before the fatal accident.
Haas has since been released from the hospital, with his father Jay telling Golf Channel the 35-year-old had been "very fortunate".
A six-time winner on the PGA Tour, Haas was in Los Angeles for the Genesis Open at Riviera Country Club. However, he has now withdrawn from the tournament.
"Last night in Pacific Palisades, California, Bill Haas was involved in a serious car accident in which the driver – a member of the family with whom Haas and his family were staying for the Genesis Open – was killed," a PGA Tour statement read.
"While Bill escaped serious injuries and has been released from the hospital, he is understandably shaken up and – more importantly – his deepest condolences go out to the host family during this tragic and difficult time.
"Bill will withdraw from the Genesis Open and plans to head home to Greenville to recover. He appreciates the support of friends, family and the golf world as a whole, and he has asked for privacy as he processes what has happened."
