Double classic winner Camelot has been retired from horse racing after getting injured in training for next month's Breeders' Cup Turf in the US.
The Ireland-based Coolmore stable said in a statement released on Monday that last year's 2000 Guineas and English Derby champion "was found to be lame pulling out this morning", meaning he wouldn't have been able to stay in training for the November 2 race at Santa Anita.
Camelot became only the third horse since Nijinsky in 1970 to achieve the Guineas-Derby double, but lost out narrowly to Encke in the St Leger in his bid to win the Triple Crown of English classics in 2012.
Camelot has struggled since then, winning just one of three starts this season after failing to recover fully from a bad bout of colic.
