In November 2009, the National Enquirer published a story claiming that Woods had had an extramarital affair with New York City nightclub manager Rachel Uchitel, who denied the claim. Two days later, around 2:30 a.m. on November 27, Woods was driving from his Florida mansion in his Cadillac Escalade SUV when he collided with a fire hydrant, a tree, and several hedges near his home. He was treated for minor facial lacerations and received a ticket for careless driving. Following intense media speculation about the cause of the accident, Woods released a statement on his website and took sole responsibility for the accident, calling it a "private matter" and crediting his wife for helping him from the car. On November 30, Woods announced that he would not be appearing at his own charity golf tournament (the Chevron World Challenge) or any other tournaments in 2009 due to his injuries.
