South Korean swimmer Park Tae-hwan's hearing over doping charges scheduled for Feb. 27 has been postponed.
 
The Korea Swimming Federation said the international swimming federation FINA has accepted Park's request to delay the hearing as he needs more time to prepare materials for explanation.
 
The new hearing schedule has not been finalized yet.
 
Park must attend a doping hearing in Lausanne, Switzerland after results of a doping test in September last year just before the Incheon Asian Games came back positive for testosterone, a banned substance.
