Kamila Valieva, the 15-year-old Russian superstar who was expected to deliver her nation its third straight Olympic gold medal in womens figure skating, practiced as usual on Thursday, hours after reports surfaced that she had tested positive for a banned substance.

Valieva tested positive for the heart medication before the Beijing Games, the Russian newspaper RBC reported.

The sample was reportedly obtained before Valieva won the European championship last month in Estonia, a performance that solidified her status as the leader of Russias quad squad of elite womens figure skaters.

Its unclear if Russia is appealing or fighting the result, though her light-hearted appearance at her regularly scheduled practice implies that the federation isnt accepting any finding that would eliminate her.
