Russia's men's quadruple sculls crew has been banned from the Rio Olympics after one of their members failed a doping test in May, the world governing body FISA said on July 1.
Sergei Fedorovtsev provided a urine sample at an out-of-competition test conducted by the Russian Anti-Doping Agency on May 17 and tested positive for the prohibited substance trimetazidine, FISA said.
While Fedorovtsev is the only crew member who tested positive, the Switzerland-based body's ban prevents the other three Russian rowers from participating in the Rio de Janiero games in August as well.
The Russian crew had won a "last-chance" regatta in Lucerne, qualifying them to compete in Rio. They will be replaced by third-placed New Zealand.
FISA said Fedorovtsev's "A" and "B" samples tested positive for the substance, which is a banned metabolic modulator. The "B" sample was tested on June 30.
