Timeline: How Kamila Valieva's Beijing Olympics doping controversy erupted

Russian teenage figure skating sensation Kamila Valieva was on Monday cleared by the Court of Arbitration for Sport to continue competing in the Beijing Olympics despite failing a doping test.

This is how the controversy surrounding the 15-year-old unfolded:

December 25, 2021: Valieva has a sample collected while competing at the Russian Championships in Saint Petersburg. It is sent for testing to a laboratory in Stockholm accredited by the World Anti Doping Agency (WADA). It detects the presence of trimetazidine, a metabolic agent used for the treatment of angina but banned by WADA because it can increase blood flow efficiency and help endurance.

February 7, 2022: Valieva becomes the first woman to land a quadruple jump in Olympic competition and in the process leads the Russians to gold in the figure skating team event at the Beijing Olympics.

February 8: The medals ceremony for the team competition fails to take place - the first sign that something is amiss. Laboratory reports to a positive test to Russian anti-doping agency RUSADA.

February 9: Behind closed doors, RUSADA suspends Valieva. She appeals and later the same day the suspension is lifted, allowing her to carry on competing. International Olympic Committee spokesman Mark Adams cites a "legal consultation" for the medals ceremony failing to take place. Reports emerge that Valieva has tested positive for a banned substance but there is no official confirmation.

The ‘Inside The Games’ website names Valieva as the figure skater at the centre of a doping probe which is delaying the awarding of medals.

February 11: Valieva practises on the rink in Beijing even as speculation swirls. The International Testing Agency, who carry out test for the Olympics, confirms
