Ernest Hemingway will only run in Thursday's Betfred Dante Stakes at York if the ground dries out and his Investec Derby preparation is also in doubt.
The Galileo colt won by a full 10 lengths on his only start to date at Dundalk and is a best priced 25-1 for the Investec Derby at Epsom next month.
He is due to test his credentials in the recognised trial on the Knavesmire on Thursday, but his participation is ground dependant.
Speaking at a press morning at Ballydoyle, trainer Aidan O'Brien said: "Ernest Hemingway is in the Dante, but he would only go to York if the ground was good or better. It is doubtful he would go to Epsom if he misses York."
