In an announcement on his Web site Tuesday that came as no surprise, Woods said he would not play the British Open next week because his injuries have not fully healed.
"Unfortunately, I've been advised that I should not play in the British Open," Woods said. "As I stated at the AT&T National, I am only going to come back when I'm 100 percent ready. I do not want to risk further injury. That's different for me, but I'm being smarter this time.
"I'm very disappointed and want to express my regrets to the British Open fans."
It will be the second time in the past four years that Woods has missed two majors in one season -- he also missed June's U.S. Open. He did not play the British Open and PGA Championship in 2008 while recovering from reconstructive surgery on his left knee. These injuries are not as easy to describe.
Woods said in May that he suffered "minor injuries" to knee ligaments and his Achilles while hitting from an awkward stance in the pine straw on the 17th fairway in the third round at the Masters Tournament. He skipped the Wells Fargo Championship, and withdrew after nine holes from The Players Championship a week later because of injury.
Woods said last week it was a mistake to go to The Players, and that if he had waited, he would be playing golf right now.
"In hindsight, I probably shouldn't have competed at The Players, but it's a big event, and I wanted to be there to support the tour," he said. "I've got to learn from what I did there and do it right this time and not come back until I'm ready."
Woods was replaced at Royal St. George's by Jason Dufner.
Brendan Jones was the next alternate, but the Australian told the Royal & Ancient he would not be able to play because his wife is expecting their first child.
Woods called R&A chief executive Peter Dawson to tell him he would not be playing.
"I know how disappointed Tiger is not to be able to play in the Open this year," Dawson said. "Naturally, we are sorry that a player of his caliber isn't able to join us at Royal St. George's, but we wish him well in his recovery and hope to see him back soon, competing in front of the fans that love to see him play the game."
Woods tied for fourth in the 2003 British Open, the last time it was played at Royal St. George's.
