Tiger Woods has pulled out of The Open.
The former World No1 has announced that his knee injury has failed to heal sufficiently in time, for him to make a comeback at Royal St George's in Sandwich, Kent, next week.
Woods said: "Unfortunately I've been advised not to play in The open. As I stated at the AT&T National, I am only going to come back when I am 100 per cent 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 fans."
Woods will be repalced by American Jason Duffner.
Chief Executive of the R&A, Peter Dawson said: "I know how disappointed Tiger is not to be able to play in The Open this year. We are sorry that a player of his calibre 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."
Tiger has slumped to 17th in golf's world rankings and could soon fall outside the top 30 if he continues to miss events.
Tiger irritated an old knee injury when hitting a shot from the pine needles at The Masters in April. He has failed to show his Major-winning form since his controversial private life came under scrutiny 18 months ago.
He has now divorced wife Elin and his form has been inconsistent since the revelations about his numerous affairs emerged.
