Aidan O’Brien has declared Constitution River, Hawk Mountain and Flushing Meadows for Saturday’s Coral-Eclipse at Sandown, with Causeway left out of the final field.
The seven-runner Group 1 Coral-Eclipse now has a sharper Ballydoyle shape than the midweek picture suggested.
French Derby winner Constitution River and Chantilly runner-up Hawk Mountain are both in, while Flushing Meadows gives O’Brien a third Coolmore runner in a race he has dominated repeatedly.
Owen Burrows relies on Gethin, back at Sandown after chasing home Ombudsman in the Brigadier Gerard, and Roger Varian sends Saddadd, who already owns smart course-and-distance form from the Gordon Richards Stakes.
Sandown Clash Gains Final Shape

Donnacha O’Brien is represented by A Boy Named Susie, fourth behind Constitution River and Hawk Mountain in the Prix du Jockey Club, while Harry Charlton’s King’s Gambit completes the declared field.
The key change is Causeway’s absence. Earlier in the week, Ballydoyle still had several moving pieces around the Eclipse and German Derby, but the final declarations leave O’Brien with a direct three-runner attack on Sandown’s midsummer championship.
According to the PA Media report carried by Yahoo Sports, Flushing Meadows joins the two headline O’Brien colts, with Causeway not declared.
That sets up a clean generational test:
Classic three-year-old form through Constitution River and Hawk Mountain against older, proven Sandown opposition in Gethin and Saddadd. For O’Brien, it is also another chance to tighten his grip on a race that has become one of Ballydoyle’s most reliable summer targets.
