Kamila Valieva, the Russian figure skating star at the center of a doping scandal threatening to overshadow the competitions at the Beijing Games, returned to the ice at an Olympic practice rink on Saturday, hitting quadruple jump after quadruple jump as she prepared for an event from which she may soon be barred.
Valieva’s status as a competitor in the Games is in doubt after it was revealed Friday that she had tested positive for a banned drug in December, a finding that — if it had not been delayed more than six weeks — would have made her ineligible to compete in Beijing.
