ADAM KIRBY has been banned for seven days by a British Horseracing Authority disciplinary panel after being found guilty of breaching the Rules of Racing at Kempton last month.
However, Kirby feels aggrieved over the matter, describing it as a "slur on his character".
The jockey was referred to the BHA on Thursday over his ride on the John Butler-trained Pipers Piping, and was found not to have taken all reasonable and permissible measures to ensure that the gelding ran on its merits when 10th in a handicap on December 5.
The on-course stewards did not hold an inquiry on the day, but the ride was subsequently reviewed by the BHA.
Kirby, 24, has been in electric form on the all-weather circuit of late, but was found in breach of rule (B)59.4.
He said: "I'm a little bit upset about it.
"The horse isn't any cop whatsoever and I rode the way I did to get him to run well. He ran well. As soon as you get vigorous with him he stops. He was well beaten before and after so it's a shame."
In an interview with At The Races, Kirby went on: "I had Christopher Stewart-Moore with me and he did a good job, but there you go.
"It's a slur on my character. I don't prevent horses from winning, I didn't prevent him from winning, I rode him the way I did to get him to run well."
