Alberto Contador's doping hearing at the Court of Arbitration for Sport has been set for 21-24 November.

The World Anti-Doping Agency (Wada) and world cycling's governing body UCI are appealing against the Spanish Cycling Federation's decision to acquit him.

The 28-year-old's case was due to be heard before CAS in June but was initially delayed until August.

The hearing will consider Contador's positive test for clenbuterol after the 2010 Tour de France.

The Spanish rider won that race by 39 seconds, ahead of Andy Schleck.

Contador faces a possible two-year ban and losing his Tour de France victory if the Lausanne-based court finds against him.

He was found to have minute traces of clenbuterol in his urine samples days before the Tour began last July.

Clenbuterol is a banned fat-burning, muscle-building drug, but the Spanish cycling federation accepted Contador's explanation that he had inadvertently consumed the drug in contaminated beef.

Wada regards clenbuterol as a zero-tolerance drug, although its rules allow athletes to escape a sanction if they prove "no fault or negligence" on their part.
