The U.S. Anti-Doping Agency has said that Lance Armstrong would have to open up completely about doping under oath if he expected his lifetime ban from cycling to be lifted. 

According to Brent Schrotenboer of USA Today, the historic cyclist will not interview with the USADA, but intends to "cooperate fully" with other anti-doping institutions.

Armstrong has said he would like to help clean up cycling, but he apparently won't meet Wednesday's deadline to tell all about the use of performance-enhancing drugs in the sport.

In an interview with Oprah Winfrey in January, the 41-year-old admitted for the first time that he had used PEDs during his cycling career. He had denied accusations for years, including when he was stripped of his seven Tour de France titles by the USADA. He has had a longstanding feud with the USADA and suggested all along that the process was more of a witch hunt than an investigation for the truth.

While Armstrong came clean in January, some still believed he wasn't completely honest or forthright about all the accusations. He didn't completely apologize to some people he hurt during his denials, most notably Betsy Andreu, the wife of Armstrong's former teammate, Frankie.

It appears that—even after the interview with Oprah—Armstrong's use of PEDs and the insults he flung at people during the USADA investigation will never die down. As he said in the Oprah interview, he will have to live with this the rest of his life.

Once one of the most celebrated athletes in the world, Armstrong now finds himself continuing to battle with an anti-doping agency while he tries to pick up the pieces of his shattered cycling career.
