Police in Florida plan to question Tiger Woods on Saturday about the events surrounding a car accident outside the golf champion's house, CNN reported.

Woods, the world's top golfer and a major sports marketing star, hit a fire hydrant and tree early Friday as he pulled his Cadillac Escalade out of the driveway of his house in Windermere, Florida, near Orlando, the Florida Highway Patrol said.

He was treated at a nearby hospital with what police described as "serious injuries", but the golfer's office said the accident was minor and that Woods had been released from the hospital in good condition after being treated.

CNN said on Saturday that investigators would question Woods, 33, who made a triumphant return to professional golf this year after missing much of last season following reconstructive knee surgery.

Windermere Police Chief Daniel Saylor told CNN on Friday that Woods was bleeding from the mouth and was "in and out of it for several minutes" when police arrived at his home shortly after the accident.

He "was on the ground, semi-unconscious and had lacerations to the upper and lower lips," Saylor said, adding that Woods's wife, Elin Nordegren, used a golf club to smash a window of his SUV to get him out.

Nordegren "explained to my officers that the doors were locked and she could not gain entry" into the crashed vehicle, so she "used a golf club" to smash a window, he said.

Woods was the only passenger in the vehicle, Saylor said.

The accident was not alcohol-related, the FHP said. "The crash remains under investigation and charges are pending," it said.

Woods's office, in a statement published on his website, said: "He was admitted, treated and released today in good condition. We appreciate very much everyone's thoughts and well wishes."

Woods is perhaps the world's richest athlete and the biggest draw on the PGA tour as he chases Jack Nicklaus's record for victories in major tournaments and the unofficial title of best golfer ever. He has won 71 times on the PGA tour in a glittering career that includes 14 major wins.

He returned to action in February this year after being sidelined for eight months due to the knee surgery, and finished on top of the FedEx Cup standings for the season.

The Orlando Sentinel newspaper, citing the highway patrol, reported that the airbags in the Cadillac did not deploy, an indication that the car was traveling under 33 mph (53 kph).

"Basically it was facial lacerations, and as I'm understanding it, nothing that serious," Windermere Mayor Gary Bruhn told CNN.
