Last start Sussex Stakes winner Mohaather has run his last race.
The Shadwell Stud-owned son of Showcasing has suffered bone bruising to his near-hind fetlock and is now set for a place at stud.
Mohaather won five of his eight starts for trainer Marcus Tregoning – four of them at Group level.
Angus Gold, racing manager for Sheikh Hamdan al Maktoum, told the Racing Post it is a disappointing way to finish on the track for Mohaather.
“It’s really sad that his career has been cut short, but it could have been two weeks before Goodwood and we’d never have seen what he could do,” Gold said.
“It was great to see him rewarded with a Group 1, and to win it in that fashion and show how good he was. The dramatic manner he won it in made it more special and showcased his turn of foot.
“Mohaather won a Group race all three years he was in training and he was an interesting horse because he was neat and athletic, looking like he might be more a seven-furlong type.
“Yet he proved he saw out the mile well and the other thing was he handled soft ground as a two-year-old, but Jim said this year he moved even better on top of the ground.
“It’s unusual to be so versatile in my experience, while the first thing Jim (Crowley) said after Goodwood was the horse definitely had the speed to win a Group 1 over six furlongs.”
