Andrea Iannone has lost his appeal to the Court of Arbitration for Sport against his suspension for failing a drug test.
The CAS ruled that Iannone had failed to prove that he had ingested drostanolone, the banned substance that had appeared in the urine sample taken from him after the Sepang race, as a result of eating contaminated meat.
Both Iannone and the WADA (World Anti-Doping Agency) had appealed against the 18-month suspension imposed by the FIM’s International Disciplinary Court (CDI).
