Damien Oliver's immediate future will be decided today, when Victorian stewards rule on a penalty for the jockey, who has admitted betting offences.
Racing Victoria will also reveal why Oliver was allowed to ride during the spring carnival, when it became known he was under investigation for illegal betting.
Oliver was stood down last week after he made admissions he bet on Miss Octopussy in a race at Moonee Valley two years ago in which he rode sixth-placed Europa Point.
He has also been charged with using a mobile phone in the vicinity of the jockeys' room before that race.
Between the reports surfacing and charges being laid, Oliver rode three group one winners at the Melbourne Spring Carnival.
