Ante-post favourite Al Riffa will not run in in Saturday's Irish 2,000 Guineas after suffering "a little setback" in training.

A son of Wootton Bassett, he made three starts last year for Joseph O'Brien, all at the Curragh, and signed off the campaign with a length-and-a-quarter success over Proud And Regal in the Group 1 National Stakes.
