Kew Gardens will be entrusted with giving trainer Aidan O'Brien a ninth win in the Coronation Cup at Epsom on May 31 after the Ballydoyle trainer revealed Magical would stay at home to run at the Curragh this weekend.
The pair had been dominating the ante-post betting for the Group 1 on Oaks Friday and, following the news, Kew Gardens shortened to 7-4 favourite despite having been trounced in the Chester mud by Morando in the Ormonde Stakes.
O'Brien said: "We just needed to test him on the left-handed track after the disappointment in the Derby at Epsom last year. I've been very happy with him and he will go for the Coronation Cup."
John Gosden, who won his first Coronation Cup last year with Cracksman, could be double-handed with the fillies Lah Ti Dar, who won the Middleton Stakes at York last week, and Coronet, who was fourth in Newmarket's Jockey Club Stakes recently.
He said: "Lah Ti Dar was running over very much her minimum trip and got the job done, and has come out of the race in great order.
"The Jockey Club Stakes turned into a three-furlong dash which didn't suit Coronet, and both will stay in the Coronation Cup."
Roger Varian, who won the race with Postponed three years ago, is looking to run Defoe after working him on Tuesday morning.
"I have never known him in better form," said the Newmarket trainer. "But he could do with a drop of rain before the race."
Salouen, who gave Cracksman a fright in the race last year, was reported on course for another bid in the 1m4f Group 1 after his impressive winning return in Listed company at Ascot this month.
Trainer Sylvester Kirk said: "Hopefully he has improved a little from four to five and he is very straightforward to deal with. He just missed out in the top races last year and his owner loves going to the big gigs. It would be nice for him to be rewarded with a big one."
Hughie Morrison also confirmed his John Porter winner and Melbourne Cup runner-up Marmelo on course to contest the Coronation and in "excellent form" having moved forward for his Newbury return.
