LOUISVILLE, Ky. (AP) Trainer Bob Baffert was suspended for two years by Churchill Downs on Wednesday after an additional drug test of Medina Spirit confirmed the presence of the steroid betamethasone in the Kentucky Derby winners system.

Disqualification of Medina Spirit could be next. The Kentucky Horse Racing Commission is still completing its investigation before making that ruling.

But Baffert will not be able to enter any horses in the Kentucky Derby or other races at the storied Louisville track through the spring of 2023. Churchill Downs says it reserves the right to extend Bafferts suspension if he has any other violations in other states. Baffert has had five in the past 13 months.

Churchill Downs initially suspended Baffert indefinitely pending the investigation. Maryland racing officials allowed Medina Spirit and Baffert-trained Concert Tour to run in the Preakness on May 15 only after undergoing three rounds of prerace testing, while New York banned Baffert indefinitely and prevented him from entering any horses in the Belmont Stakes.

Reckless practices and substance violations that jeopardize the safety of our equine and human athletes or compromise the integrity of our sport are not acceptable and as a company we must take measures to demonstrate that they will not be tolerated, Churchill Downs Inc. CEO Bill Carstanjen said. Mr. Bafferts record of testing failures threatens public confidence in thoroughbred racing and the reputation of the Kentucky Derby. Given these repeated failures over the last year, including the increasingly extraordinary explanations, we firmly believe that asserting our rights to impose these measures is our duty and responsibility.

Earlier Wednesday, lawyers for Baffert and Medina Spirit owner Amr Zedan confirmed the split-sample test came back positive for betamethasone.
