Windermere, Florida (CNN) -- Pro golfer Tiger Woods says he bears sole responsibility for an early-morning car accident, but state police said he has canceled a Sunday interview with investigators looking into the crash.
In a statement issued Sunday afternoon on his Web site, Woods offered no details of his Friday-morning wreck outside his Windermere, Florida, home except to say he suffered cuts and bruises and was "pretty sore."
"This situation is my fault, and it's obviously embarrassing to my family and me," he said. "I'm human and I'm not perfect. I will certainly make sure this doesn't happen again."
The 33-year-old golf phenomenon has won the Masters tournament and the PGA tournament each four times, as well as three U.S. Open Championships. According to a police report, he pulled out of his driveway about 2:25 a.m. Friday in a 2009 Cadillac SUV and struck a fire hydrant, then a tree.
Authorities have said they don't have details on why Woods was driving away from his home at such an early hour, but a police report said the wreck was not alcohol-related. Opinion: Tiger Woods is only human
State troopers have asked to question him three times about the wreck, but they have yet to be successful, with Woods canceling a third scheduled interview Sunday, Florida Highway Patrol spokeswoman Sgt. Kim Montes told CNN.
Woods' agent, Mark Steinberg, said in a statement: "We have been informed by the Florida Highway Patrol that further discussion with them is both voluntary and optional.
"Although Tiger realizes that there is a great deal of public curiosity, it has been conveyed to FHP that he simply has nothing more to add and wishes to protect the privacy of his family."
Under Florida law, Woods must show his license, registration and proof of insurance to police, but he is not obligated to give a statement on the crash.
"If we're unable to meet with him, we'll move on with our investigation," Montes said. She called the delays "very unusual, because it's such a minor accident."

Investigators sought possible surveillance tapes of the accident from neighbors, but none were found, Montes said.
In his statement, Woods praised his wife, Elin Nordegren, whom he said "acted courageously when she saw I was hurt and in trouble." Nordegren told police she used a golf club to break out the rear window of the vehicle, then pulled Woods from the SUV after she heard the accident from inside their home.
But he said, "This is a private matter, and I want to keep it that way."
"The only person responsible for the accident is me," he said.
Woods and his wife have two children, a 2-year-old and a baby born in February.
The statement did not address whether he would play in this week's Chevron World Challenge in California. Woods is a four-time winner of the tournament, which helps raise money for Tiger Woods Foundation programs.
When asked whether would attend the tournament, Steinberg told CNN it "has not been determined at this point in time."
