Aidan O’Brien firms up Coral-Eclipse runners but could divert one to complete awesome Derby Grand Slam

Aidan O'Brien has confirmed that both Constitution River and Hawk Mountain will run in the Coral-Eclipse, but there's a possibility he might divert one of them to the Derby, aiming for a historic Grand Slam. Hawk Mountain, though a contender, seems less likely to shift, while Constitution River, the French Derby winner, is being considered for the Derby. This move could make O'Brien the first trainer to achieve a Derby Grand Slam, which would be a monumental achievement in horse racing.
