LONDON - Olympic heptathlon champion Jessica Ennis-Hill admits she would have doubts over Russian athletes if they are allowed to take part in the Rio Games. Russia is currently banned after a World Anti-Doping Agency report revealed "state-sponsored" doping in the country. British star Ennis-Hill says the country would compete under a cloud of suspicion. "I hope if it does get to that stage where there are Russian athletes competing in Rio in the Olympics, really drastic measures have been put in place to make sure that nothing like this happens again," Ennis-Hill told the BBC. "I'd be lying if I would say that I wouldn't look at Russian athletes and think, 'Is everything 100 per cent OK?' because that's just natural to feel like that after these situations have arisen."
