Lance Armstrong once predicted his possible demise

• Armstrong was asked in 2005 what would happen if he got caught in a doping scandal
• CNN to air documentary that includes that testimony on Saturday night
• Armstrong denies doping throughout sworn deposition, possibly committing perjury in the process

Lance Armstrong once eerily predicted what would happen to himself if he ever got caught in a doping scandal. He said he would lose all of his sponsors and that people who trusted him would lose faith in him, even cancer survivors.

He said so under oath in deposition testimony from 2005. After obtaining the video of that testimony, the producers of an Australian documentary about Armstrong now will have it broadcast on CNN Oct. 27.

Though Armstrong has denied doping allegations for more than a decade, this time the famed cyclist is under oath, possibly committing perjury in a dramatic show of defiance for the world to see in the documentary entitled The World According to Lance Armstrong.

Much of the content of his testimony previously was made public in writing, but the video provides further context and takes on new meaning in light of recent events. Two weeks ago, the U.S. Anti-Doping Agency released a massive evidence file that said Armstrong led a long-running conspiracy to use banned drugs and blood transfusions to boost performance.

"What the testimony shows is Lance Armstrong's willingness to perjure himself -- and not just once but repeatedly, again and again and again," said Quentin McDermott, who reported the documentary. "What it also demonstrates very clearly is his willingness to smear and vilify those eyewitnesses who were prepared to tell the truth."

Armstrong denies doping throughout the deposition testimony, which is part of a legal proceeding he filed against an insurance company that refused to pay him performance bonuses.

The most chilling part comes when he's asked what would happen if he were found to be guilty of doping. He's asked if sponsorship agreements would go away.

"All of them," Armstrong testified on Nov. 30, 2005. "And the faith of all the cancer survivors around the world. So everything I do off of the bike would go away too. And don't think for a second I don't understand that. It's not about money for me. Everything. It's also about the faith that people have put in me over the years. So all of that would be erased. So I don't need it to say in a contract you're fired if you test positive. That's not as important as losing the support of hundreds of millions of people."

Seven years later, much of his prediction has come true. On Oct. 10, USADA released a giant dossier of witness statements and scientific data that said Armstrong used sophisticated doping methods to gain an edge and avoid testing positive.

After the evidence came out, all of his major sponsors announced they would terminate their relationships with him. Armstrong also stepped down as chairman of Livestrong, his foundation for cancer survivors. Last Monday, the International Cycling Union (UCI) endorsed USADA's decision to ban him for life and strip him of his seven titles in the Tour deFrance. Friday, UCI called on Armstrong to return nearly $4 million in prize money.

Armstrong's testimony came at the height of his fame – right after winning seven consecutive Tour de France titles from 1999 to 2005. During the deposition, Armstrong is by turns "confident, fluent, arrogant, combative and cocky," as described by McDermott, an Australian investigative reporter. Armstrong's lambastes his accusers, characterizing one of them – his masseuse – as a "whore."

"In one sense it is a tour de force -- a supremely confident display by a sportsman who clearly, at the time, regarded himself as untouchable," McDermott told USA TODAY Sports.

The documentary first aired in Australia on Oct. 15. Saturday, it will compete for attention with the World Series and college football. But it rides a wave of disastrous news about Armstrong, once considered an American hero.

Former cycling teammates Frankie Andreu and Tyler Hamilton are among those interviewed in the documentary. Andreu's wife Betsy, now an Armstrong enemy, describes him as "the Bernie Madoff of sport."

Armstrong's prediction concludes the documentary.

"It is a stunningly prophetic forecast of his own demise," McDermott said.
