She finished seventh at the 2006 World Cup.
After her return to competition, she failed a second drugs test - for bromantan in February 2012, and was handed a lifetime ban by the Russian Anti-Doping Agency RUSADA.
Chernova successfully appealed the decision in a Russian court, but the ban was subsequently confirmed following a counter-appeal by the World Anti-Doping Agency to the Court of Arbitration for Sport.
