European 400m individual medley champion Ilya Borodin has been ruled out of the Tokyo Olympics after testing positive for COVID-19, Russian team officials said. 
Borodin, 18, who was expected to contend for a medal, failed a test during a final training camp in Vladivostok before departing for Japan. 

“European champion Ilya Borodin passed a positive test for Covid-19, which is why he will not take part in the Olympic Games in Tokyo,” the Russian Swimming Federation said.
