LANCE Armstrong has until February 6 to do something he has always resisted - co-operate fully with the US Anti-Doping Agency - and is being lured by the promise his lifetime ban from sport will be reconsidered.
In setting the deadline, USADA boss Travis Tygart claimed the ex-cyclist told fresh lies in his selective confessional to Oprah Winfrey.
Armstrong's insistence that he rode clean after returning to the sport in 2009 - he made his comeback that year at Adelaide's Tour Down Under - and his assertion he only used a small amount of blood-booster EPO, have been dismissed by Tygart.
''He used a lot of EPO,'' he told American 60 Minutes after formalising his call to Armstrong to give sworn testimony.
Tygart said Armstrong would lie about being clean in his comeback because admitting he doped would leave him open to prosecution for criminal fraud under the statute of limitations. He has written to Armstrong demanding he co-operate ''fully and truthfully'' if he wants his lifetime ban from sport reduced. If Armstrong does not agree, he will be condemned to the penalty Tygart announced last October and be disqualified from sanctioned sporting events forever.
Armstrong's lawyer, Tim Herman, said Armstrong was unlikely to talk to USADA and would more likely front the UCI's ''truth and reconciliation'' commission.
In his interview with Winfrey, Armstrong argued it was unjust that he had received the ''death penalty'' while other confessed dopers served far more lenient sanctions. The key difference is while other cyclists have provided USADA with evidence, the seven-time winner of the Tour de France has, until the Oprah interview, flatly denied his sins.
