Sheikh Mohammed's Dubai Millennium succumbed to equine grass sickness Sunday evening. According to John Ferguson, Sheikh Mohammed's bloodstock advisor, "Dubai Millennium became uncomfortable on Sunday night, and it was evident that a third emergency surgery was necessary."This was performed by Huw Neal and Dan Hawkins at Greenwood, Ellis, and Partners at Newmarket."It soon became clear that there were complications of the intestinal tract that were inoperable," Ferguson said. "His prospects were hopeless, and on humane grounds. Dubai Millennium was not allowed to recover from the anaesthetic. The horse was the most marvelous patient, and everyone who knew him is very sad to see him go."Five-year-old Dubai Millennium, by Seeking the Gold out of Colorado Dancer, will be buried in the stallion graveyard at Sheikh Mohammed's Dalham Hall Stud, where he was foaled and stood as a stallion. He will lie next to maternal grandsire Shareef Dancer.
