Adayar will not return to the scene of his career-defining Derby victory on the Queen's Platinum Jubilee weekend.
Top trainer Charlie Appleby was gearing the colt towards the Coronation Cup at the big summer event. A setback held up his training for the Group 1 race on June 3, which will now come too soon.
“Adayar, who was an intended runner [at Epsom], met with a minor setback in the respect that he was coughing for a few days so I eased off him for a week,” Appleby told godolphin.com. “In doing so, he did very well that week so I think we're going to be giving the Coronation Cup a miss as fitness wise I won't have him there ready in time. He will most likely head to the Prince of Wales’s Stakes.
