Due to injuries sustained in a one-car accident last week, Tiger Woods will be unable to play in the 2009 Chevron World Challenge.
“I am extremely disappointed that I will not be at my tournament this week,” Woods said. “I am certain it will be an outstanding event and I’m very sorry that I can’t be there.”
“We support Tiger’s decision and are confident the strong field and excellent course will provide an exciting week of competition at the Chevron World Challenge, said Greg McLaughlin, Tiger Woods Foundation President & CEO
Woods will not participate in any other tournaments in 2009 and will return to action next year.
The Golf Channel’s Rex Hoggard is reporting that because of headaches and soreness he was advised not to play or travel.

Perhaps it’s due to injuries, and perhaps it’s because his wife hasn’t yet stopped yelling at him.
