Aidan O'Brien says a "computer error" led to Albert Einstein and Gstaad being mistakenly scratched from the Newmarket 2000 Guineas.
The much-vaunted Albert Einstein headed ante-post lists for the Rowley Mile Classic prior to his disappointing reverse in Saturday's Gladness Stakes at the Curragh, after which the Ballydoyle handler suggested his charge could revert to sprinting but a final decision on his Newmarket participation would be made in due course.
Gstaad, winner of the Coventry Stakes at Royal Ascot last summer and the Breeders' Cup Juvenile Turf at the end of his two-year-old campaign, looked well placed to assume the position of O'Brien's chief hope of winning an 11th 2000 Guineas after pleasing connections in a racecourse gallop at the Curragh on Sunday.
However, he too was scratched from the 2 May showpiece on Tuesday morning.
When contacted, for a response, O'Brien said: "It's a computer error, we're trying to get them back in."
