Three-time British classic winner Camelot, most recently seventh in the Qatar Prix de l'Arc de Triomphe (Fr-I), is being treated for colic, according to a Twitter post from Coolmore Stud.
The posting said the Two Thousand Guineas (Eng-I) and Investec English Derby (Eng-I) winner trained by Aidan O'Brien had undergone exploratory surgery late Oct. 11, and that more information would be released Oct. 12.
"Triple Classic winner Camelot was admitted to Fethard Veterinary Hospital this evening and underwent exploratory colic surgery," the Tweet said. "Obviously it's still very early days but a further bulletin will be released in the morning."
Camelot, a son of Montjeu who was upset in his bid to sweep the English Triple Crown in the Ladbrokes St. Leger (Eng-I) in September, was never a factor in the Oct. 7 Arc at Lonchamp in France.
