Former Godolphin trainer Mahmood Al Zarooni has lodged an appeal to reduce the length of his eight-year suspension for doping offences, the British Horseracing Authority (BHA) announced on Tuesday. The 37-year-old Emirati was found to have given banned anabolic steroids to 15 horses in his care at a BHA hearing last month. He was charged with rule breaches related to prohibited substances, duty to keep medication records, and conduct prejudicial to racing. In a statement released on Tuesday, the BHA said Al Zarooni had decided to contest the length of his ban, adding that a date for the appeal hearing would be announced in due course.
