Golden Horn will "definitely" run in the King George VI And Queen Elizabeth Stakes at Ascot on Saturday week as long as conditions are suitable, said owner Anthony Oppenheimer.
Connections of the Investec Derby winner said they would monitor the colt's well-being before committing to the esteemed Group One after he secured victory in the Coral-Eclipse at Sandown on 4 July.
Trainer John Gosden and Oppenheimer are now happy to run the son of Cape Cross at Ascot under the proviso that the ground does not get too demanding.
Oppenheimer said: "We've definitely decided to run next week as long as the ground is not very soft or heavy.
"Hopefully the weather will stay as it has been, nice and fine.
"The list of horses to have done what he is attempting is elite and it would be very nice to create history.
"Having sponsored the race for many years through De Beers it would extra special if he won it.
"He showed he was versatile at Sandown, making all the running.
"It was a tough way for him to do it but he came through again."
Only Nashwan, Mill Reef and Tulyar have won the Derby, Eclipse and King George in the same season.
Golden Horn proved his stamina over a mile and a half when winning the Investec Derby in fine style.
That form was then given a boost when runner-up Jack Hobbs ran out an easy winner of the Irish Derby.
Golden Horn then dropped in trip to tackle his elders in the mile-and-a-quarter Coral-Eclipse.
Frankie Dettori adopted different tactics in the small field by making all of the running, but the outcome was no less impressive as he claimed a three-and-a-half-length victory over The Grey Gatsby.
Gosden's inmate is the odds-on favourite for Ascot's midsummer showpiece over a mile and a half.
