Irish 2000 Guineas hero Magician is to be left in the Investec Derby at the confirmation stage on Monday.
Previously impressive in winning the Dee Stakes at Chester over 10 furlongs, the Aidan O'Brien-trained colt dropped back to a mile on Saturday and ran out a stunning winner of the Curragh Classic.
Afterwards, Coolmore supremo John Magnier suggested "tongue in cheek" that he could go for the Derby, although Royal Ascot and the St James's Palace Stakes would be the more obvious route.
Speaking at the Curragh on Sunday, O'Brien said: "He pulled out fine from the race and he'll be left in the Derby tomorrow.
"The lads haven't made a decision yet. They'll get all the information about how he is and then make a decision. It's definitely possible.
"It (a mile and a half) would be a bit of a concern with what he did yesterday as he showed so much speed, but he got a mile and a quarter easily at Chester and he has a relaxed way of galloping."
Of his Derby squad, O'Brien added: "They'll all be left in but I'm not sure about Nevis."
