Russian ice hockey star Ilya Kovalchuk on Tuesday told his country’s clean athletes to make sure they took part in the 2018 Pyeongchang winter Olympics if they satisfied strict conditions that showed they had a doping-free background. He was speaking after the International Olympic Committee (IOC) said on Tuesday it had banned Russia from the 2018 Pyeongchang Winter Olympics after evidence emerged of an “unprecedented systematic manipulation” of the anti-doping system.
