Aidan O'Brien revealed today that heavy ground could rule Duke Of Marmalade out of Tuesday's Juddmonte International Stakes at York.

Speaking after the victory of King Of Rome at Leopardstown the master of Ballydoyle said that a decision would be reached tomorrow about his participation.

"The ground is going to be heavy and deep. He's in now but he has to be a doubt. It's far from ideal and will be totally against him

"But knowing the horse he is the lads might let him run. We'll talk about it tomorrow and make a decision."
