Embattled jockey Danny Nikolic must wait until at least Monday to learn if he still has a career in racing after the postponement on Wednesday of the hearing of charges against him.

Nikolic, 37, is alleged to have threatened Victoria's chief racing steward Terry Bailey in an incident at last week's Seymour races that has amounted to a case of his word against Bailey's.

The allegations were first aired officially when Nikolic applied last Wednesday for a stay of proceedings against Bailey's decision to stand him down from riding.

During that hearing it was alleged Nikolic had said to Bailey: "We all have families ....., and we know where yours lives...."

Nikolic denied the allegation, claiming it was Bailey who had threatened him.

No independent verification of either allegation has been offered.

The Racing Appeals and Disciplinary (RAD) Board chaired by former judge Russell Lewis rejected Nikolic's stay application, saying it preferred Bailey's evidence, but made no specific finding either way.

As a result of Nikolic's alleged threat and other incidents at Seymour, the stewards laid two charges against him on Monday.

One charge falls under a rule of racing dealing with "improper or dishonourable action or practice" and the other with "conduct prejudicial to the image, interests, or welfare of racing".

It had been intended that the same RAD panel that ruled against Nikolic last week would adjudicate on those charges.

But with the respective parties assembled to commence the hearing on Wednesday, Lewis announced a legal issue had made it necessary for a different panel to be convened.

The postponement follows newspaper reports attributed to Nikolic's family and friends that he expects to ultimately receive a ban that would effectively end his career.
