Hermival is reported to have returned to France "sore" following his disappointing performance in the Irish 2,000 Guineas.
The Mikel Delzangles-trained colt was considered a major contender after placing third behind Camelot and compatriot French Fifteen in the 2000 Guineas at Newmarket, but was well beaten in sixth.
Delzangles feels there are excuses for the below-par effort and he will now be considered for a trip to Royal Ascot along with stable companion Dragon Pulse, who suffered similar problems in the French 2000 Guineas.
"Hermival came back very sore in his back and hopefully that explains the poor run," said Delzangles. "We will try to sort that out and, if we do, we will then make a decision whether to run him in the St James's Palace Stakes at Royal Ascot or go for the Prix Jean Prat.
"Those two races are also the options for Dragon Pulse, but it will not necessarily be one horse in one race and one horse in the other, as they have different owners.
"We will see how both horses are when the races are coming up and then decide."
