The running of two horses at Bendigo on Saturday with incorrect jockeys and saddle cloth numbers "was completely unacceptable", says Racing Victoria's executive general manager of integrity Jamie Stier.

Trainer Tom Dabernig was fined $3000 after pleading guilty to negligence when two Lindsay Park horses – Independent Road and Peidra – ran in the listed Bendigo Guineas with each other's saddle cloth numbers and jockeys on board.

Dabernig self-reported the mix-up after the race in which Independent Road, a $61 chance with Jye McNeil incorrectly on board, finished 13th and Peidra, rated $51 with Regan Bayliss riding, finished last.

The two three-year-olds are both bay/brown geldings, although Peidra is darker in colour. Independent Road was meant to carry 59kg, one kilogram more than Peidra.
