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.
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."
The suspension will run from Friday January 18 to 24 inclusive.
