Two Bendigo Guineas runners from the Lindsay Park stable have been disqualified from the race after they were incorrectly saddled.

The error was not picked up by the starters when checking the brands before the race while Lindsay Park co-trainer Tom Dabernig was fined $3000 for the mistake.

Racing Victoria deputy chief steward Rob Montgomery said Independent Road and Peidra ran in Saturday's race and later disqualified after each had finished near the tail of the field.

Regan Bayliss was to ride Indepentant Road but he ended up on Peidra.

Jye McNeil was booked for Peidra and partnered Independant Road.

Both horses finished unplaced in the race won by Riddle Me That.

The error wasn't picked up until after the running of the Golden Mile when Dabernig self-reported to stewards.

"Mr Dabernig came and reported it to us after race eight after one of his staff reported it to him," Montgomery said.

"It was an honest mistake but a costly one."

Montgomery said the starters, Corey Mallyon and Errol Gath, would be referred to RV's human resources department.
