The Court of Arbitration for Sport says a Russian boxer and Romanian weightlifter will lose medals from the Rio de Janeiro Olympics after failing doping tests at the games.

Misha Aloian won a flyweight silver medal in a bout on the final day of the Olympics in August and tested positive for the banned stimulant tuaminoheptane.

Gabriel Sincraian, who won bronze in the men's 85-kilogram weightlifting, tested positive for exogenous testosterone.

CAS says both athletes have been disqualified.
