Sole Power will not run in Saturday's Diamond Jubilee Stakes at Royal Ascot following his brilliant display in the King's Stand on Tuesday.
The Eddie Lynam-trained seven-year-old clinched the five-furlong (1000m) Group One for the second successive year and it was suggested afterwards he could bid for the big sprint double won by Australian horse Choisir in 2003.
However, a change of heart on the back of a hard race means Sole Power is now set to head straight for the July Cup at Newmarket, a race in which he finished fifth last summer.
Lynam still has a major contender for the Diamond Jubilee in stable companion Slade Power who made an impressive return in the Greenlands Stakes at the Curragh last month.
"He doesn't run. He's in great form but a bit tired," Lynam said.
"We'll think about Newmarket."
