Kamila Valieva, one of the Olympics’ youngest and biggest stars, will take to the ice on Tuesday and, if all goes as she plans, perform spinning jump after spinning jump on her way to an expected victory in women’s figure skating’s signature event. But if she succeeds, she will not receive a medal. And neither will any of her competitors.

Olympic officials, faced with perhaps the most fraught controversy at these Winter Games, said on Monday that they planned to withhold medals in any event in which Valieva, 15, places in the top three until after her doping case is resolved, perhaps months from now.
