A rush of stud retirements have been announced among the top echelon of northern hemisphere performers in the UK and America.
Among the top class stallions going to stud are G1 winners Camelot, Dullahan and Reckless Abandon.
Coolmore announced the retirement of triple classic winner Camelot due to the injury he suffered while training for next month's Breeders' Cup Turf in the US.
Coolmore said that last year's 2000 Guineas, English Derby and Irish Derby champion was lame and could not stay in training for the November 2 race at Santa Anita.
Camelot became only the third horse since Nijinsky in 1970 to achieve the 2000 Guineas-Epsom Derby double.
He then attempted to emulate Nijinsky by completing the Triple Crown in the St Leger at Doncaster but lost narrowly to Encke.
Camelot won only once in three starts this season after suffering from a severe bout of colic.
“Unfortunately we never saw the same brilliance on the racecourse as we had before his colic operation but he was
showing signs of it at home in recent weeks,” said trainer Aidan O’Brien.“It’s obviously disappointing that he won’t get the opportunity to run again.”
Camelot’s last start was a fourth in the G1 Prince Of Wale’s Stakes at Royal Ascot.
The son of Montjeu from Tarfah (Kingmambo), bought for 520,000gns at the 2010 Tattersalls October Yearling Sale Book One, wil start his breeding carer at Coolmore in 2014.
• Last year's two-year-old champion Reckless Abandon has been retired to stand at Kildangan Stud in Ireland in 2014.
Trained by Clive Cox, Reckless Abandon won all his five starts at two including a G1 double in the Prix Morny and Middle Park Stakes.
This year the son of Exchange Rate competed with honours in the Temple Stakes and G1 King's Stand Stakes before winding up with a fifth in the G1 Prix de l'Abbaye.
• Multiple US G1 winner Dullahan has been retired from racing after suffering a tendon injury.
Dullahan, by Even the Score, beat Game On Dude and other older horses in the G1 Pacific Classic in his three-year-old season.
He also won the G1 Dixiana Breeders’ Futurity in 2011 and GI Blue Grass Stakes at Keeneland in 2012 before running third in the Kentucky Derby. He won or placed in nine of his 18 starts for $1,735,901.
Trainer Dale Romans said: “I don’t think we ever got to see him at his very best, he might have been the most talented colt I ever trained.”
Dullahan, a half-brother to Kentucky Derby winner Mine That Bird, will be shipped to WinStar Farm in Kentucky for rehabilitation while 2014 stud plans are resolved.
• Shantaram, a Group winning son of champion sire Galileo, will stand at Coolagown Stud in Ireland in 2014.
The winner of two of his six starts, the four-year-old won the G3 Bahrain Trophy at Newmarket last year.
