 Alberto Contador |
The CAS said in a statement that it granted "a request for a second exchange of written submissions between the parties as well as for a new procedural calendar.
"As a consequence of the parties' request, the hearing which was scheduled for 1, 2 and 3 August 2011 is cancelled and will be rescheduled for new dates, probably in November 2011."
The CAS said the request was made by the World Anti-Doping Agency and supported by the other three parties involved in the case.
The WADA and the ruling cycling body UCI are challenging the acquittal of Contador by the Spanish cycling federation.
Contador tested positive for clenbuterol during the 2010 Tour de France which he went on to win. He escaped a ban, stating that he took in the substance via contaminated beef.
If found guilty of a doping offence by CAS, Contador faces a ban and would be stripped of his 2010 Tour title and all results since being acquitted earlier this year, including the 2011 Giro d'Italia title and fifth place at the latest Tour which ended Sunday.
The CAS said the new round of written submissions will allow the parties to complete their evidence and arguments in connection with certain scientific issues.
