The New York State Racing and Wagering Board on Wednesday revoked the license of Richard Dutrow Jr., who trained the 2008 Kentucky Derby winner, Big Brown, and barred him from New York racetracks for at least 10 years.

The board cited Dutrow’s long history of transgressions in prohibiting him from the sport. According to records kept by the Association of Racing Commissioners International, Dutrow has been cited 64 times in 9 states and at 15 tracks for a varied list of incidents, including multiple medication violations.
