Plans for Elarqam remain fluid following his disappointing effort in the Irish 2,000 Guineas a fortnight ago.
Mark Johnston's charge was a hot favourite for the Curragh Classic after his fourth placed finish in the Guineas at Newmarket, but the son of Frankel out of the brilliant mare Attraction finished a well-beaten sixth.
Subsequent tests have failed to reveal any significant abnormalities and connections are now in a quandary over whether to continue down the Group One path or lower his sights.
Charlie Johnston, assistant to his father, said: "We gave him the once over and there were no orthopaedic or soundness issues. We scoped him and it came back a little bit dirty, but nothing has come to light to explain that sort of performance.
"He has been back cantering since last Sunday and seems well and fine. He was beaten at halfway. We went there knowing if he ran to his Newmarket level he would go very close. He ran a stone below it. Quite why, we don't know. At this stage, we've just got to suck it up and move on.
"I'm sure dad will want to speak to Angus Gold (racing manager) and Sheikh Hamdan (owner). There are two clear different routes to go down and that is come down in class and try to get his head back in front , or to keep campaigning him like a Guineas fourth and throw him back in the deep end somewhere. We've let the dust settle from Ireland and we will sit down with the Shadwell team in the next week or two and decide which route we go down."
