Woods pulls out of PGA Tour event in Napa

Tiger Woods has withdrawn from this week's PGA Tour event and will not play at next month's Turkish Airlines Open, delaying his comeback after 14 months out following back surgeries.

The 14-times major champion announced on Monday that his game was not sharp enough for him to compete in the Safeway Open in Napa, California, on Thursday or the European Tour event in Turkey.

"After a lot of soul searching and honest reflection, I know that I am not yet ready to play on the PGA Tour or compete in Turkey," he said.

"My health is good, and I feel strong, but my game is vulnerable and not where it needs to be."

Woods, 40, said the comeback delay was not due to back-related issues.

"I practised the last several days in California, but after a lot of hours, I knew I wasn't ready to compete against the best golfers in the world," he said.

"I will continue to work hard, and plan to play at my foundation's event, the Hero World Challenge, in Albany (Bahamas in December)."

His friend, former tour player Notah Begay, said Woods' preparation had been hindered last week by Hurricane Matthew, which passed not far offshore from his south Florida residence.

"We had a candid conversation this morning and he was extremely disappointed," Begay said on Golf Channel.

"He has a standard of performance like no one else and he just doesn't feel like it's ready."
