Danny Nikolic will know on Friday whether he can ride headline mare Mosheen the following day after failing in his bid for a stay of proceedings against an indefinite ban.
The Racing Appeals and Disciplinary (RAD) Board rejected Nikolic's bid on Wednesday to have the ban lifted and set the date for his appeal.
In an often bitter and tense hearing before the RAD Board, chief steward Terry Bailey claimed Nikolic had threatened him and his family, had launched a torrent of abuse against him and had attempted to intimidate him during Tuesday's Seymour race meeting.
As a result, Bailey had banned Nikolic from riding indefinitely.
Nikolic countered with claims that Bailey had threatened to end his career and had fabricated the evidence against him.
The tribunal heard that the issue began as Nikolic rode to the starting gates for a race at Seymour and called out to Bailey as he passed him: "Keep your eyes on the road, Terry."
Bailey later questioned Nikolic over the comment, asking him if he was making a threat.
Nikolic replied that it was a line from a television advertisement and it was meant as a joke.
According to evidence from both sides the issue then escalated before the next race when Bailey was about to take his position in the steward's tower.
Bailey told the tribunal Nikolic approached him and said: "We've all got families c... and we know where yours lives c..."
Nikolic described the allegation as "outrageous" telling the tribunal it had been Bailey who issued the threat telling the jockey: "I told you I would f... your career."
He said he had no idea why Bailey would make false claims against him and that "everyone knows I'm fond of families".
The tribunal heard Tuesday's incident came on top of revelations connecting Nikolic with allegedly fixed races and after the jockey has been questioned in relation to a murder.
RAD chairman Russell Lewis said his board preferred the evidence of the chief steward.
