So You Think has been retired to stand at stud in Australia after lameness ruled him out of the Coral-Eclipse at Sandown on Saturday.
The Aidan O'Brien-trained six-year-old would have been aiming to land back-to-back renewals of the Group One contest over a mile and a quarter, which was due to be his final run before returning to his native Australia.
So You Think had been in outstanding form this season with consecutive Group One victories in the Tattersalls Gold Cup at the Curragh and the Prince of Wales's Stakes at Royal Ascot.
