The Court of Arbitration for Sport has accepted a settlement between Russian bobsleigh athlete Nadezhda Sergeeva and the governing IBSF in an anti-doping case from the 2018 Winter Olympic Games.
Sergeeva was disqualified from the two-woman bob event in February in PyeongChang, where she finished 12th, after testing positive for trimetazidine.
But while she accepted the anti-doping violation, the IBSF agreed "the very low concentration of the prohibited substance was likely to have been caused by an unsuspicious contaminated supplement which she had obtained from an official and supposedly reliable source".
Sergeeva has been given an eight-month ban dating from her positive test which will expire on October 22.
At the Winter Games, Russian curler Aleksandr Krushelnitckii, Japanese short-track skater Kei Saito and Slovenian ice-hockey player Zuga Jeglic also failed doping tests.
