MELBOURNE Cup placegetter Jakkalberry's racing career is over.
His English trainer Marco Botti says injury had forced the Australian Thoroughbred Bloodstockowned stayer into retirement.
Jakkalberry appeared on track for another World Cup campaign in Dubai and perhaps a second tile at the Melbourne after a comeback win at Wolverhampton earlier this month.
It was the eightyearold's first race since suffering a tendon injury after winning group 2 City of Gold in Dubai in March last year a setback which forced him to miss a return trip to Australia in the spring.
Jakkalberry ran third in the 2012 Melbourne Cup in a major breakthrough for the Ballandistrict syndicator ATB.
His future is now expected to be at stud.
"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<" Botti said on his website.
"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," Botti said.
Jakkalberry won 12 of 29 starts for more than $2m in earnings.
His wins included the 2012 US St Leger and a group 1 event in Italy.
The entire also races in Hong Kong and Japan.
