Kamaal was identified as support personnel in the original case involving the horse Glenmorgan, which was first tackled in 2012.

Ridden at an 160 kilometre endurance race at Al Wathba, United Arab Emirates, by Sheikh Hazza bin Sultan bin Zayed Al Nahyan, the horse tested positive for propoxyphene, a pain relieving substance, and its metabolite norpropoxyphene.

The Emirati rider challenged a 27-month suspension awarded by the FEI Tribunal for the positive test at the February 2012 event at the Court of Arbitration for Sport (CAS).

His suspension was reduced to 18 months following his appeal.

During the proceedings Kamaal confirmed he had administered the product fustex, which contains propoxyphene, to the horse the night prior to the event.

This led to disciplinary proceedings being opened against him by the FEI in November 2015, with a provisional suspension being placed on the doctor.

An FEI Tribunal has now announced he has been handed a two-year suspension in line with the governing body's anti-doping rules.

The sanction has been backdated to the start of the provisional suspension, which means Kamaal will not be able to act as support personnel through to November 15, 2017.

Kamaal will also have to pay a fine of CHF2,500 (£2,000/$2,500/€2,300) and costs of CHF1,000 (£820/$988/€933), which were imposed by the FEI Tribunal.

He has 30 days from the date of notification, which came on January 13, to appeal the verdict to the CAS.

Following the original case, the FEI issued a communique which urged caution over the use of Fustex, which can be used to promote muscle growth.

The governing body said a lack of knowledge regarding the ingredients of the Argentinian product would not be a valid excuse in any anti-doping procedures.

Ongoing concerns over horse welfare in the United Arab Emirates led to the FEI stripping the nation of hosting rights to last year's World Endurance Championships.

The event was instead held in Slovakia.
