Michael Kinane misses the mount on Ciro in today's Irish Derby after failing to recover from a back injury picked up yesterday.
George Duffield will take the ride.
Kinane tweaked a muscle in his back when Spinning Top finished seventh in the Pretty Polly Stakes.
Aidan O'Brien revealed that his stable jockey informed him on the way to the course that he would not be able to ride today.
'Mick wouldn't be here unless he is 150 per cent.' said O'Brien.
