Russian figure skater Kamila Valieva has been cleared to compete at the Winter Olympics in Beijing after the Court of Arbitration for Sport ruled that she should not be provisionally suspended.
It emerged last week that the 15-year-old tested positive for the banned substance trimetazidine on Christmas Day last year, resulting in an provisional suspension until February 8.
However, the Russian Anti-Doping Agency lifted the ban the following day - something which the International Olympic Committee, World Anti-Doping Agency and International Skating Union appealed against.
However, CAS has now rejected that appeal, clearing Valieva to compete in Tuesday's women's individual figure skating competition.
"The athlete should benefit from the following exceptional circumstances. She is under 16 and a protected person under the WADA code," said CAS director general Matthieu Reeb.
The ruling added: "Such late notification was not her fault, in the middle of the Olympic Winter Games."
Valieva is the heavy favourite to win gold in Tuesday's event, while she has already helped the Russian Olympic Committee to gold in the team event - a result which remains under scrutiny.
