Toby’s Corner, upset winner of the Wood Memorial who was forced to miss the Kentucky Derby due to lameness in his right hind leg, was to begin walking under tack on Thursday at trainer Graham Motion’s barn at the Fair Hill Training Center. Toby’s Corner underwent a nuclear bone scan on Tuesday at the New Bolton Equine Clinic and the results did not show any structural damage. Motion said Dr. Dean Richardson gave him the green light to begin putting the tack on the colt, who was to ship back to Fair Hill on Wednesday afternoon. “We’re going to go on with him,” Motion said. “We never really found out what was wrong with him.” On May 2, five days before the Kentucky Derby, Motion noticed that Toby’s Corner was lame in his right hind leg and decided not to send the horse to Louisville for the race. Motion said in a perfect world, he would be able to get Toby’s Corner ready for a race like the Travers at Saratoga in August with a prep race beforehand.
