Injury has forced the retirement of globetrotting stayer Jakkalberry, an American St Leger winner and third in the 2012 Melbourne Cup.
Jakkalberry was being prepared for the Dubai carnival following his comeback win at Wolverhampton last week but trainer Marco Botti reported he had pulled up sore after a morning work-out.
The trainer said it was hoped the eight-year-old, who is owned by Australian Thoroughbred Bloodstock, would be sent to stud.
"He came home from his win at Wolverhampton in great form and all was looking set for Dubai, where we had planned to take him to win the Group Two City of Gold for the second year," Botti said on his website.
"He returned back from exercise this morning a little sore, exploratory tests have told us that this is the time to call it a day with him.
"He is fine in himself and in great spirits, but it would be unfair to keep persevering with him.
"He has been a great horse for all of the team, he ran so well in the Melbourne Cup, this has to be one of the many highlights in his career.
"He has been a delight to train and we have had some brilliant fun with his supportive owners, Australian Thoroughbred Bloodstock. We would hope to now find him a job as a stallion."
