• Professional Australian motorcycle racer Anthony West has denied any wrongdoing after being notified that he tested positive for stimulants in a sample taken at the FIM SuperSport World Championships, San Marino, on 8 July. ‘I have two choices before me: admit to something I didn’t do, or fight the anti-doping ruling’, he said in a statement posted on Facebook. ‘In 2013, I was in violation after taking a nutritional supplement that I didn’t realise contained a banned substance. I admitted my mistake and accepted my punishment. After that situation, I stopped taking nutritional supplements for fear of failing a test. Now, I fail a test and I have no idea why. We are looking into the best, and fastest, way to proceed. I just want to get this situation resolved and get back on track. After nearly twenty years in the World Championships, I have never used any substances to try and artificially improve my on track performance.’
