Swedish professional golfer Jesper Parnevik says he owes Elin Nordegren an apology for introducing her to now-husband Tiger Woods.

"We probably thought he was a better guy than he is," Parnevik told the Golf Channel from West Palm Beach, Fla., where he is in the final stage of PGA Tour qualifying.

It is the most critical public comment to date from one of Woods' colleagues, who once employed Nordegren as a nanny for his family.

Parnevik made the comments amid rumours that surfaced last week, alleging Woods was unfaithful to Nordegren, with whom he has two children.

On Thursday, a third woman denied tabloid reports that she had an affair with Woods.

Kalika Moquin told Us Magazine that she had met Woods through her job as a manager at a Las Vegas nightclub, but she says the accusations are "completely untrue."

The lawyer for the first of the women to be accused of having an affair with Woods cancelled a press conference planned for Thursday in Los Angeles.

Rachel Uchitel, a nightclub hostess from New York has denied reports she was involved with him, and was expected to address the allegation at the news conference, which had been scheduled for Thursday afternoon.

She had been accused of having an affair with the world's No. 1 golfer in a story by tabloid The National Enquirer, last week.

The office of her lawyer, Gloria Allred, said it the news conference had been cancelled "due to unforeseen circumstances." The statement did not elaborate on what the circumstances were.

"There will be no further statements on this matter," Allded's office said.

TMZ claimed it is the first time in Allred's career that she cancelled a news conference.

Tabloids accused Uchitel of having first met with the golfer in June at a Manhattan nightclub, and then visiting him during a recent trip to Australia. But Uchitel said she had met Woods only twice while working as a hostess. She admitted she was in Melbourne at the same time Woods was in Australia for a tournament, but said her trip had nothing to do with Woods.

"It's the most ridiculous story," she told The New York Post earlier this week. "I work in clubs and I am a businesswoman. I do not have sex with celebrities, and I have not had an affair with Tiger Woods."

The second woman, cocktail waitress Jamiee Grubbs, who claims she had a three-year affair with Woods, released a tape to celebrity magazine Us Weekly. In the call, a man urges a woman to delete her name from her voicemail and warns her that his wife may soon be calling.

The voice has not been verified as that of Tiger Woods.

Meanwhile, the day after Woods issued a surprise public apology Wednesday for unspecified "personal failings," there are reports that say Woods is offering his wife as much as US$60 million to remain married with him for another two years.

Woods did not mention allegations of the affair in the statement, but said he would deal with his "behaviour and personal failings" alone with his family.

One way he's doing this, according to the Chicago Sun-Times newspaper, is by revisiting a pre-nuptial agreement he signed with Nordegren, in 2005.

In that agreement, the couple reportedly agreed that Nordegren would receive $20 million if she remained married to Woods for 10 years. According to the Sun Times, that amount has been increased "substantially."

And the Daily Beast website - a news and opinion site published by former Vanity Fair and New Yorker editor Tina Brown -- quotes an unnamed source saying Woods agreed to immediately transfer $5 million into Nordegren's personal bank account.

The entire saga erupted last Friday after Woods crashed his SUV outside his suburban Orlando home at 2:30 a.m. He says he sustained injuries from the crash, although there was no blood found in his car.

He claims Nordegren smashed a window in order to help him get out after the crash. There have been tabloid allegations that the injuries were sustained from a family dispute.
