Woods has not played since his US Open play-off triumph in June

World number one Tiger Woods will not attend this week's Ryder Cup but has pledged his support to the US team.

Captain Paul Azinger had said he planned to keep in touch with Woods during his side's campaign.

But Woods, who will miss the tournament because of a knee injury, said: "I plan to watch, but won't attend.

"Paul Azinger has my cell phone number and he or any US player can call me any time - I doubt I can do much, I have no feel for how the course is playing."

In July, Woods turned down an invite from Azinger to act as a vice-captain for the match against Europe.

In all, Woods has won 10, lost 13 and halved two of his 25 Ryder Cup matches and the 14-time major champion says he will be available to offer support should Azinger require it.

"If I can offer any assistance, I'm happy to. I wish the American team well and hope they can bring back the Cup."

Woods, whose wife Elin is expecting their second child, admits he is still some way from returning to competitive action.

He required surgery after his left knee suffered a double stress fracture.

"I just can't rotate on my leg and I still don't know what my first event will be in 2009," he said.

"I miss the competition and I miss the preparation, but if I tried to play now, you would see some of the worst shots you've ever seen.

"My rehabilitation is going well.

"Although I won't be able to swing a club until early next year, my left knee is getting stronger and the doctors are pleased with my progress."
