The International Cycling Union, the sport's governing body, is set to rule on the agency's recommendation that Armstrong be stripped of his seven Tour de France titles.
Armstrong's story -- that of a cancer survivor who tamed the grueling three-week race not once, not twice, but more than any other cyclist before or since -- made him a household name.
Then came this month's finding by the USADA of "overwhelming" evidence that he was involved as a professional cyclist in "the most sophisticated, professionalized and successful doping program."

The agency then announced it would ban Armstrong from the sport for life and strip him of his results dating from 1998. The decision wiped out 14 years of his career.
The International Olympic Committee also is reviewing the evidence and could revoke Armstrong's bronze medal from the 2000 Sydney Games.
Should the International Cycling Union concur with the USADA's recommendation, it will be up to the organizers of the Tour de France whether it will nominate alternate winners for the 1999-2005 tours. The Amaury Sport Organisation, which runs the 21-day event, has said it will decide after the ruling.
If Armstrong's name is expunged, it will leave Greg LeMond as the only American to win the tour. He did so in 1986, 1989, and 1990.
Armstrong, 41, has consistently denied the allegations.
In the past, Armstrong argued that he has taken more than 500 drug tests and never failed. In its 202-page report, the USADA said it had tested Armstrong less than 60 times and the ICU conducted about 215 tests.
"Thus the number of actual controls on Mr. Armstrong over the years appears to have been considerably fewer than the number claimed by Armstrong and his lawyers," the USADA said.
The agency didn't say that Armstrong ever failed one of those tests, only that his former teammates testified as to how they beat tests or avoided the test administrators altogether. Several riders also said team officials seemed to know when random drug tests were coming, the report said.
Speaking to participants in his cancer-fighting foundation's annual Ride for the Roses in Austin, Texas, on Sunday, Armstrong said, "People ask me a lot how are you doing. And I tell them I've been better, but I've also been worse."
In his brief remarks to the crowd, Armstrong didn't mention the recent findings by the USADA.
He stepped down last week as chairman of the Lance Armstrong Foundation, but said he will continue to be involved. Some of the foundation's donors are furious over the scandal, and want their money back.
"We will not be deterred," Armstrong said Friday night at the organization's 15th anniversary celebration in Austin, Texas. "We will move forward."
