India faces the ultimate sanction of expulsion from the Olympics unless it keeps corruption-tainted officials out of its ranks, IOC President Thomas Bach said in an interview with The Associated Press.
Former world swimming champions James Magnussen and Eamon Sullivan, and their 4x100-meter relay teammates, could face sanctions after admitting to taking the sleep medication Stilnox during a "bonding session" ahead of last year's London Games.
The World Anti-Doping Agency accepted the decision that stripped Lance Armstrong of his seven Tour de France titles, saying Friday it was the "right and proper sanction" for the disgraced American cyclist.
Controversial swimmers Nick D'Arcy and Kenrick Monk have avoided additional punishment above what the Australian Olympic Committee has already imposed on them for posting photos of themselves posing with guns on social networking sites.
The British Olympic Association conceded for the first time on Monday that athlete support for its lifetime doping ban has significantly declined ahead of a hearing that will determine the sanction's future.
The head of Britain's Olympic committee wants an independent review of the World Anti-Doping Agency, accusing the global body of failing to catch the worst offenders and dragging the fight against drug cheats into a "dark age."
