Trainer Ian McInnes has been banned for three years after one of his racehorses was found to have been denerved.
Commando Scott had a biaxial neurectomy to his right hindleg in July 2008. But the horse ran nine times between May and September 2009, which is against the Rules of racing.
A British Horseracing Authority (BHA) disciplinary enquiry on 10 June found McInnes guilty of “failing to conduct his business with reasonable care and skill”.
He was given a further six-month ban for misleading BHA investigating officers.
The disciplinary panel said he had “recklessly disregarded the welfare” of the horse.
