LONDON — Trainer Gerard Butler was disqualified for five years by the British Horseracing Authority (BHA) on Wednesday after nine horses in his care tested positive for the banned anabolic steroid stanozolol. Irishman Butler, based in Newmarket, England, admitted injecting horses with a product for injured joints and faced seven charges of breaching the Rules of Racing. A BHA disciplinary panel said Butler administered the prohibited substance Rexogin which contains stanozolol - the steroid used by disgraced Olympic sprinter Ben Johnson at the 1988 Seoul Olympics - to four horses using a method restricted by law to qualified surgeons. — Reuters
