KENTUCKY DERBY-winning trainer Doug O'Neill could face a suspension in California after one of his horses was found to have an elevated level of total carbon dioxide, an infraction for which he previously has been punished.

The California Horse Racing Board is considering the case, which involves "milkshaking," the illegal practice of giving a horse a blend of bicarbonate of soda, sugar and electrolytes. The mixture is designed to reduce fatigue and enhance performance.

O'Neill faces his third total carbon dioxide violation in California and fourth in a career that has spanned 25 years.

Speaking at Baltimore's Pimlico Race Course, where he is overseeing Derby winner I'll Have Another in preparation for the May 19 Preakness, O'Neill adamantly denied the charge: "I swear on my kids' eyes I never milkshaked a horse."

The California board could consider O'Neill's latest violation as early as May 24."
