US Horse of the Year retired
The reigning US Horse of the Year Harve de Grace has had to be retired after it suffered an ankle injury during a light workout at Churchill Downs.
Owner Rick Porter said the five-year-old mare's trainers noticed that there was a problem with the right front leg and called in the vets who assessed the Grade I Woodward Stakes winner and relayed the bad news.
He said: "Owning Grace through her racing career has been the highlight of my time in horse racing.
"She was a wonderful, wonderful racehorse and I feel confident she'll be an equally wonderful broodmare."
Havre de Grace won nine out of 16 starts through her career, earning more than $2.6 million (£1.6 million) in prize money, including $150,000 for her only outing this year at the New Orleans Ladies Stakes.
Mr Porter said that he wished the Kentucky-bred horse a long and happy retirement.
