St Nicholas Abbey dies
St Nicholas Abbey, Aidan O'Brien's triple Coronation Cup hero, died on Tuesday morning, confirmed Coolmore.
The brilliant seven-year-old, winner of six races at the highest level, had to be put down after he suffered a bout of colic.
A statement issued by Coolmore read: "Regretfully St Nicholas Abbey has lost his brave battle after suffering a colic this morning.
"Surgery revealed a severe strangulating colon torsion that was unviable and he had to be euthanized on humane grounds."
