The United States Anti-Doping Agency's chief Travis Tygart has told the French sports daily L'Equipe his agency will be sending Lance Armstrong's file to cycling's world governing body this week to get the American rider's life ban ratified.
Armstrong was stripped of his record seven Tour de France wins last month and handed a lifetime ban after indicating that he would not challenge charges that he had doped throughout his career.
Armstrong has always denied doping.
The USADA sanction needs to be confirmed by the International Cycling Union who said earlier this month they had no intention of appealing against the decision to ban Armstrong.
