Trainer Sir Mark Todd has had his license temporarily suspended while investigations continue into the circumstances of the video showing him striking a horse with what appears to be a branch.
The two-time Olympic gold medalist event rider, voted rider of the 20th century by the International Federation for Equestrian Sports, is not contesting the ban.
A British Horseracing Authority statement read: "The chair of British racing's Independent Judicial Panel has today (Feb. 16) approved an application from the BHA that an interim suspension should be placed on the training license of Sir Mark Todd following the emergence over the weekend of a video showing him striking a horse with what appears to be a branch.
"This interim suspension means that while investigations continue into the circumstances of this incident, Sir Mark will be unable to race horses in Britain or internationally.
"The trainer has admitted the individual involved in the video was him, has apologized for his actions, and agreed to the imposition of an interim suspension."
The suspension means Todd will not be able to run Cape Cornwall Rose, who was entered at Lingfield on Friday. Earlier this week Todd issued a public apology and stepped down as a patron of World Horse Welfare. The Racing Post understands the BHA will be inspecting Todd's yard on Feb. 17.
The statement continued: "The BHA will provide further updates as necessary in due course, though will not be able to comment on the detail of the investigation itself until it is concluded.
"The interim suspension has been approved on the basis that it can be reviewed at a later date if necessary, on application by either party."
Todd, the BHA, and National Trainers Federation all declined to comment further when contacted by the Racing Post on Wednesday.
