Paco Boy will not race in the Betfred Sprint Cup at Haydock on Saturday, but will go to France instead.
Trainer Richard Hannon said that the five-year-old will race in Sunday's Prix du Moulin on a mile circuit instead of six furlongs on Merseyside.
"We have weighed up the options and, while we don't have to declare until tomorrow, it now looks almost certain that we are going to give the Sprint Cup a miss and wait for the Prix du Moulin at Longchamp," said Hannon.
"I have always favoured France, but I have spoken to part-owner Derek Lucy-Smith and he agrees the Moulin is probably the right race for him.
"My worry about Haydock is that it could develop into a messy race as there will be a big field and they will most certainly split into two groups, so if you are drawn in the wrong place you could be in trouble.
"They will also go off very fast and while Richard Hughes makes the point that Paco Boy was quick enough to finish best of all in the July Cup at Newmarket last year, Equiano and Starspangledbanner are likely to go five-furlong pace at Haydock and we won't be able to ride a race on our fellow.
"In contrast, there will be a single figure field for the Moulin. There is no Goldikova and while Makfi could run, the ground will be vastly different to the very soft conditions he revelled in when beating us in the Prix Jacques le Marois at Deauville, so we must have a chance of turning that form around."
