Trainer John Gosden has confirmed that Golden Horn is highly likely to be supplemented for the Investec Derby.
It will cost £75,000 to add the Betfred Dante Stakes winner to the field for the premier Classic, but the Newmarket handler told the Guardian that would be the case following discussions with owner Anthony Oppenheimer.
The Prix du Jockey Club over 10-and-a-half furlongs had been considered the more likely target before the performance of the Cape Cross colt on the Knavesmire, where he beat stablemate and pre-race Derby favourite Jack Hobbs.
Gosden said: "Quite correctly, he wanted to wait to see how the horse came out of the race. But I'm very happy.
"That [supplementing] will be the decision, we will go ahead and supplement the horse.
"Obviously, we don't do that until five days before the race, so, as long as everything's all right then and everything's in order, we are planning to run the horse."
He added: "He's a handy horse, he's well balanced, so he suits the race, really. As long as he switches off, he should get the trip well."
