Accenture will no longer sponsor Tiger Woods following the revelations about his private life, the company announced.

Woods announced on Friday that he would take an "indefinite break" from golf after admitting his infidelity.

The 33-year-old, who is married to Swedish former model Elin Nordegren, has been swamped by a series of affair allegations since crashing his car in mysterious circumstances on November 27.

A statement on Accenture's website read: "For the past six years, Accenture and Tiger Woods have had a very successful sponsorship arrangement and his achievements on the golf course have been a powerful metaphor for business success in Accenture's advertising.

"However, given the circumstances of the last two weeks, after careful consideration and analysis, the company has determined that he is no longer the right representative for its advertising."

Accenture's announcement follows Gillette's admission that Woods was no longer appearing in their advertising.

Gillette initially said it would be "limiting his role" in marketing to "support his desire for privacy", but spokesman Damon Jones later appeared to distance the company even further.

Jones said on Radio Five Live: "Who knows what will happen in the future? We're not speculating. (But) our actions are clear. We have a brand ambassador who we have said is no longer going to appear in our advertising.

"That is a pretty clear statement about where we are going. Actions speak louder than words."

US phone firm AT&T has said it is "presently evaluating our ongoing relationship" with Woods but main sponsor Nike said it was standing firm and offered him their "full support".

Woods' long-time caddie Steve Williams had earlier insisted he had no knowledge of any of the player's extra-marital relationships.

"I had no knowledge of what Tiger's indiscretion was," Williams told the Sunday News in New Zealand.

"I am an honest person. I had no knowledge of what was going on. If I did, I would say I did.

"What people fail to realise is I [just] work for Tiger Woods. I live in New Zealand, I travel to and from New Zealand to caddie for Tiger Woods. I am not with him 24/7.

"Whilst I am a very good friend of his I don't know what he does off the course.

"When he is not competing, I am back in New Zealand. I have no knowledge of what he is doing."

Williams backed Woods' decision to focus his attention on saving his marriage and remains committed to the troubled star.

"Tiger just said he needs a break and I don't want to put any pressure on the guy," he said.

"He will know in his mind, and his family will know in their mind, when it is the right time for him to return to playing golf."

Meanwhile, Peter Alliss, for many people the voice of golf, believes that if Woods does not play for the next six months he might never play again.

Alliss, a former Ryder Cup player who has been television's best-known commentator on the game for over 30 years, has described Woods as being in "dreadful turmoil" and just wonders what the future holds.

"I don't envy anybody involved in this, it's all very horrid and very public," the 78-year-old said on the BBC website.

"It must be remembered that this is the time of the year when he has in the past taken time off.

"But if he doesn't play for the first six months of next year then he might have decided he's come to the end of the road.

"He's going to have to put up with a lot of nonsense and ridicule and comment for the next 20 to 30 years and it depends how well he tackles that.

"He's in a very, nasty awkward position of his own making, I'm afraid.

"If we learn come the end of February that he's not going to play in The Masters at Augusta in April and maybe not in our Open Championship in July then it's getting very serious.

"Then you have to wonder about all sorts of things that we're not privy to - his state of mind, whether he wants to continue, whether he's thinking of early retirement."
