Amateur jockey Rob James was last night handed a four-month ban from the sport.
A video emerged last week of James mimicking riding on a recently deceased horse.
James has since apologised for the video, which was recorded in 2016.
The I-H-R-B handed down a 12-month ban from racing, with the last eight months suspended.
It follows on from the incident where trainer Gordon Elliott was banned for a year with the last six months suspended.
He also received a fine of 15,000.
