The International Olympic Committee responded by saying that no medals would be awarded in any event in which Valieva finished in the top three.Losing the case means the U.S. skaters will receive their medals months, maybe even years, from now after Valieva's case is decided. She led the Russians to a convincing victory in the team event. If that result is overturned, the U.S. would get gold medals.The skaters had argued, without success, that they should at least receive the silvers before Sunday night's closing ceremony. In a letter sent to IOC President Thomas Bach that was obtained by The Associated Press, the skaters' attorney argued that the IOC’s “own rules mandate that a victory ceremony ‘to present medals to the athletes shall follow the conclusion of each sports event.’”
