DES MOINES, Iowa (AP) – The owners of third-place Kentucky Derby finisher Dullahan say the colt won’t be running in the Preakness Stakes on May 19.  Trainer Dale Romans says the Preakness would be Dullahan’s third race in just five weeks and the horse would be “best served” by sitting it out.  Dullahan will run next in the Belmont Stakes on June 9, the final leg of the Triple Crown races.
