LAUSANNE, Switzerland - The IOC is urging Lance Armstrong to provide evidence of his drug use to anti-doping bodies in order to "bring an end to this dark episode."
The IOC says it "unreservedly condemns" the actions of Armstrong, who admitted in an interview with Oprah Winfrey that he had doped throughout his cycling career.
The International Olympic Committee calls it "a very sad day for sport," but lessons should be learned to ensure a level playing field for athletes.
The IOC says "we now urge Armstrong to present all the evidence he has to the appropriate anti-doping authorities so that we can bring an end to this dark episode and move forward, stronger and cleaner."
On Thursday, the IOC stripped Armstrong of his bronze medal from the 2000 Sydney Olympics.
UCI: Armstrong confession repairs damage to sport
The International Cycling Union says Armstrong's confession of doping is "an important step" toward repairing the damage he did to cycling.
UCI President Pat McQuaid says Armstrong confronting his past, in an interview with talk-show host Oprah Winfrey, moves cycling "forward on the long road" to restoring confidence in the sport.
McQuaid said the UCI would welcome Armstrong participating in a proposed "truth and reconciliation process" for cycling. Armstrong told Winfrey he took banned drugs during each of the seven Tour de France victories that were stripped from him for cheating.
McQuaid said Armstrong "confirmed there was no collusion or conspiracy between the UCI and Lance Armstrong."
Armstrong reportedly paid the UCI $125,000, which former teammates testified was in exchange for covering up suspicious drug tests.
