ROME (AP) -- World Anti-Doping Agency lab experts will meet to consider changing its rules regarding clenbuterol, the drug that Alberto Contador tested positive for at last year's Tour de France.
Contador said he inadvertently consumed the substance in contaminated meat and was cleared by the Spanish cycling federation earlier this year. An appeal by WADA and the International Cycling Federation to the Court of Arbitration for Sport will be heard in August.
WADA science director Olivier Rabin says the meeting in Montreal next week could lead to the installment of a fixed level of clenbuterol over which no excuses are valid.
Rabin would not say how any possible rule changes could affect Contador's case.
