O’Neill Could be Suspended for TCO2 Violation
Trainer Doug O’Neill could face a suspension and fine stemming from a 2010 finding in California that a horse in his care had an elevated level of total carbon dioxide in his blood system.
O’Neill, the winning trainer in the May 5 Kentucky Derby Presented by Yum! Brands (gr. I) with I’ll Have Another, has had three prior TCO2 violations — two in California and one in Illinois. He served a 15-day suspension in connection with the Illinois case.
