Golden Horn will not run in the King George VI And Queen Elizabeth Stakes at Ascot this afternoon due to soft ground.
There had been a question mark over his participation in the race after a deluge of rainfall on Friday.
And after having walked the track before the meeting was due to begin, trainer John Gosden felt conditions had gone against the Derby and Coral-Eclipse hero.
The Clarehaven handler said: "Where we are standing on the straight course, this ground is fine, and will ride good to soft.
"But where they are running over a mile and a half, it runs down into Swinley Bottom - and it's not called that for nothing.
"On that part of the course, my stick was going in 10 or 12 inches and it's holding ground there.
"He's a horse with an enormous amount of speed and is an incredible athlete.
"You're asking him to be nearly a St Leger horse to go on that (ground) today."
