A hearing in the doping cases of U.S. sprinters Tim Montgomery and Chryste Gaines that had been set for next week was postponed at the request of all parties, the Court of Arbitration for Sport said.
CAS, the world's highest sports court, said a new date has not yet been set. It did not elaborate on the reason for the postponement.
The hearing, which was to begin Monday in San Francisco, is likely to last at least a week. CAS rulings are final and cannot be appealed.
