ARCADIA, Calif. – The Breeders’ Cup has altered the way in which horses not nominated as foals to the event can be permitted to participate. A payment that represents a percentage of the purse of the race to which a horse was being supplemented has been changed to a flat $100,000 fee (or $200,000 if the horse’s sire was not BC-nominated at the time of conception) that makes a horse eligible for any Breeders’ Cup race for the rest of his career.
