Three Russian biathletes failed drugs tests, the International Biathlon Union (IBU) confirmed in a statement ahead of the world championships in Pyeongchang on Friday. The trio tested positive for prohibited substances during a World Cup event in Ostersund, Sweden last December, the sport's governing body said without specifying the type of drug used.
Russian athlete Olga Pyleva was banned for two years after she tested positive for drugs at the Turin Winter Olympics.
There is never a dull moment in the sporting world and this weekend was no different.
