Taken out of the race in March before he had run, he emerged as possibly the best British-trained contender when beating Too Darn Hot in the Dante Stakes at York last week.
The Hughie Morrison-trained colt is by a Derby winner in New Approach and out of an Oaks second in Shirocco Star, who Morrison also trained.

“We had a very hard race last week at York,” said Morrison.
“There are only 16 days between that and the Derby and you have to be realistic about horses recovering and we will only find out the week after when the adrenaline comes out of the system.
“We are perfectly happy with him and he is doing everything you would like him to do after a race. We will bide our time until the latest possible point.
“If the horse did run, I would not be able to put my hand on my heart and say that he has fully recovered. It would be wrong of me to say that.
“As a three-year-old, he is definitely the best I’ve trained.
“There are other options to come. We get free entry into the Irish Derby and the Grand Prix de Paris, so we have to put that in the melting pot as well.”
