The Spanish cyclist Alberto Contador faces another hurdle in his bid to clear his name of doping allegations after the World Anti-Doping Agency said it was joining the appeal against the decision to absolve him.
Contador, three-times Tour de France champion, was cleared by the Spanish Cycling Federation last month following a positive test for clenbuterol during last year's race.
The Spaniard said the positive test came as a result of him eating contaminated meat but the International Cycling Union and now WADA have appealed the ruling to the Court of Arbitration for Sport.
Contador, who plans to ride in the Tour, is continuing to compete and won the Tour of Catalunya at the weekend.
