Lausanne - The Court of Arbitration for Sport says Spanish cyclist Alberto Contador's doping case has been postponed and will probably be heard in November.
CAS says the case won't start next Monday because the parties need more time "to complete their evidence and arguments relating to some specific scientific issues."
Contador was due in sport's highest court for a three-day hearing to consider his positive test for clenbuterol, an anabolic steroid, when winning the 2010 Tour de France.
The International Cycling Union and World Anti-Doping Agency are appealing a Spanish cycling federation decision to clear Contador in February.
A Spanish tribunal accepted Contador's explanation that he consumed clenbuterol by eating a contaminated steak.
