The United States Anti-Doping Agency (USADA) has banned three members of Lance Armstrong's former staff.
Lance Armstrong's former teammate Floyd Landis brought the suit in 2010 under a federal law.
USADA said Armstrong has been forced to come clean because of legal proceedings in the US.
Lance Armstrong had previously said he was treated unfairly and singled out.
US cyclist Tyler Hamilton's career was entangled in controversy by blood doping scandals.
Last year, the US Anti-Doping Agency published a report into Armstrong's doping programme.
