Derby hero Ruler Of
The World retired to stud
RULER OF THE WORLD, the 2013 Derby winner, has been retired and will stand at Coolmore Stud next season.
A previous injury flaring up again has led to the decision, as Ballydoyle vet John Halley said: "Ruler Of The World has a recurrence of the muscle injury in his hind quarters that he suffered earlier in the summer and although it's not critical, we have been advised that he be retired to stud."
The Aidan O'Brien-trained four-year-old has been unable to scale the same heights this season, his sole win coming in the Group 2 Prix Foy at Longchamp in September.
Sheikh Joaan Al Thani's powerful Al Shaqab Racing operation purchased a 50 per cent stake in the colt prior to his return to action in 2014 when finishing down the field in the Dubai World Cup at Meydan.
Following his win at Longchamp, Ruler Of The World then finished ninth in the Arc, before occupying the same position when last in the Champion Stakes at Ascot last weekend.
O'Brien said: "He did very well to win the Derby less than two months after making his debut and he showed himself to be equally effective over a mile and a quarter in last year's Champion Stakes."
