Kyle Calvin, trained by Michael Field and owned by his wife Marie, won €35,000 when he landed the most prestigious event at February’s National Meeting in Clonmel.
After the race, Mr Field told the internet channel Irishtv.ie he had also placed a “nice little” pre-tournament bet on the dog when it was listed at odds of 40-1. He said winning the event was “a dream of dreams”.
Subsequently, a certificate from the National Laboratory said a sample taken from the derby winner during the meeting had shown traces of ephedrine and phenylpropanolamine. Both are banned stimulants.
Mr Field was chief executive of the IGB between September 1997 and March 2003. He is also a former principal at Ard Scoil Rís in Limerick.
After the derby, Mr Field told the Sporting Press Kyle Calvin had been withdrawn from training for stud duties for a number of months to capitalise on demand.
Mr Field was contacted about the certificate yesterday. He said it was a matter for the Irish Coursing Club.
“I do not wish to make further comment,” he said.
Since late February, both he and his wife have been contacted by the Irish Examiner regarding speculation that their dog tested positive. However, on each occasion, they had not been informed of any negative result or the potential of one by the ICC.
Last week, the ICC confirmed that six dogs had tested positive for banned substances at the meeting.
A hearing committee will now be appointed and, in all likelihood, B samples will be screened by an independent laboratory.
After the meeting, Boylesports, the derby’s sponsor, and Paddy Power, said they had lost heavily on the derby outcome. In part this was because the perception was that Kyle Calvin had suffered greatly in the semi-final and was considered a major doubt for the final.
After the win, the dog’s recovery was described as “quite astonishing by any standards” by IGB’s official reporter Michael Fortune.
A report in the Sporting Press said the dog had been expected to be withdrawn but instead had produced “one of the bravest and gamiest performances ever seen at Powerstown Park”.
Under ICC rule 88, the owners of dogs deemed to have raced with a banned substance, after a hearing committee considers the case, are liable for €2,000 fine, disqualification, and forfeiture of prize money.
