Churchill will aim to get back on track in the Qatar Sussex Stakes.
Having won the 2000 Guineas at Newmarket before following up in the Irish version, the son of Galileo was a red-hot favourite for the St James's Palace Stakes at the Royal meeting.
He could only finish fourth behind Barney Roy, beaten four and a half lengths, but will take on older horses for the first time at Glorious Goodwood on August 2.
Trainer Aidan O'Brien said: "Everything has been well since Ascot and the plan for him is go to the Sussex Stakes. That's what we're aiming him at at the moment and we're very happy with him.
"Nothing came to light regarding Ascot, he seemed to be fine. It was a very hot day in Ireland and a very hot day in England, and maybe it was the combination of travelling and warm weather.
"He seems to be in good form and has come out of it well."
