Age Of Aquarius will take up stud duties once he has recovered from the leg injury that brought his racing career to a premature end on Thursday.
The four-year-old son of Galileo was tipped to develop into a worthy successor to Yeats and he demonstrated his potential when narrowly beaten by Rite Of Passage in a thrilling finish to the Ascot Gold Cup.
The Artemis Goodwood Cup was next up for the colt and he looked to be travelling well for Johnny Murtagh when he broke down with an apparent leg injury.
He was immediately attended to and was found to have torn ligaments, signalling the end of his racing career, but Aidan O'Brien has confirmed he will be saved for stud duties.
"After sustaining a serious injury in the Goodwood Cup, Age Of Aquarius was transferred to the Arundel Veterinary Hospital, where he received great care and attention, for which we are very grateful," O'Brien said via a Coolmore statement.
"He arrived back at the Fethard Equine Hospital this morning and we are delighted to report that we are going to be able to save the horse for breeding.
"Essentially he has torn ligaments at the back of his fetlock joint and, although his recuperation will be long, we hope and expect that he should be back out in a paddock in a few months.
"What has happened with Age Of Aquarius is a real shame. He was a good racehorse and one we always thought a lot of."
