Pre-race blood tests for horse found ‘not to be 100%’ Trainer running out of options for Classic prep runHigh Definition, the favourite for the Derby at Epsom next month, will miss his intended reappearance in the Lingfield Derby Trial on Saturday after pre-race blood tests “just weren’t 100%” according to Aidan O’Brien, the colt’s trainer.
High Definition has been the clear favourite for the Classic since making plenty of ground to win the Group Two Beresford Stakes at the Curragh last September going away. He was a 3-1 chance for Epsom, and one of only three colts priced up in single figures, when the news that he would miss his intended trial broke on Wednesday evening.
