Kamila Valieva is sad Winter Olympics story but British sport has its own doping problem

dailystar.co.uk:

Winter Olympics.But perhaps British sport should get its own house in order before people single out one person from Russia who has tested positive for the banned angina drug trimetazidine.I'm not condoning what Valieva has done, because she shouldn't be allowed on the ice in Beijing.But we have more pressing issues to deal with on our own doorstep, following the bombshell revelations from former Rugby League stars Ollie Wilkes and Jamie Acton that they were involved in widespread doping throughout their careers.Those who follow the sport have spent years marvelling at how these supreme athletes put their bodies on the line week in, week out to cope with the demands of what is a brutal business.But in one fell swoop, Wilkes and Acton have called into serious question the integrity of an entire sport, tarnished the good names of all those who remain clean and left the game's rulers facing more questions than answers.Wilkes, who captained Scotland, revealed he was taking illegal substances at the time he secured a 'dream' move to Wigan, claims coaches used to encourage stars to go missing when UCAD testers turned up at clubs, and said one team-mate even injected himself in his car en-route to a training session.Acton, meanwhile, took to social media to accuse Rugby League of going to great lengths to keep drug use a secret.The timing of these damaging admissions and allegations is horrendous.The new Super League season began last weekend with fireworks and fanfare, while a Rugby League World Cup will take place on these shores in the autumn.Wilkes is now being lauded in some quarters as some sort of brave whistleblower.
