Three of Lance Armstrong's former associates Tuesday received lifetime bans from Olympic sports for their involvement in what the United States Anti-Doping Agency has called a widespread doping conspiracy on Armstrong's Tour de France-winning teams.

Luis Garcia del Moral, a team doctor on the U.S. Postal Service team; Michele Ferrari, a consulting doctor to riders on the USPS and Discovery Channel teams; and Pepi Marti, a trainer on the teams, were banned after not responding to official charges levied by USADA last month.

They were charged with administering performance-enhancing drugs and blood transfusions, trafficking in banned substances and covering up the use of banned substances or blood doping while working with those squads.

Armstrong, team manager Johan Bruyneel and former USPS team doctor Pedro Celaya have also been charged with participating in the scheme.

Armstrong, who insists he is not guilty, has until Saturday to decide if he will accept the charges or contest them and go to arbitration. If he accepts the charges, he would be stripped of his seven Tour titles. Armstrong has gone to federal court to stop the process.

Note

• Cofidis rider Remy Di Gregorio of France was arrested at the team hotel in Bourg-en-Bresse and suspended by his team.

Police made their move on the Tour de France's first rest day, with judicial officials saying two other people suspected of supplying Di Gregorio, 26, with banned substances were also arrested.

Di Gregorio's arrest comes after an investigation that began in June 2011 and is led by the French police agency responsible for doping investigations, OCLAESP, and Marseille police.
