Zawraq will not run in the Derrinstown Stud Derby Trial on Sunday.
The Dermot Weld-trained colt is as low as 6-1 for the Investec Derby on June 6 and was expected to put the finishing touches to his preparation this weekend.
However, a combination of likely heavy ground at Leopardstown and the fact the Sheikh Hamdan Al Maktoum-owned three-year-old missed a piece of work last week means connections have decided to give the noted trial a miss.
Regular rider Pat Smullen is also suspended.
Angus Gold, the owner's racing manager, said: "He's not going to run this weekend.
"He missed a bit of work last week and while I saw him this morning and he worked very well, Pat Smullen said that he didn't really feel in love with the soft ground when he won the other day.
"There is water everywhere around the Curragh at the moment and while it should be dry tomorrow, there is more rain forecast and the ground is already heavy at Leopardstown.
"Having missed a piece of work and then running on bad ground, he may subject himself to a harder race than ideal just three weeks before the Derby.
"He's still in the Irish Guineas, which is an option, but we could just decide to take him for a bit of work somewhere 10 days beforehand and then a decision will be made if Epsom is the direction we go in.
"We don't want to risk leaving his season behind this weekend, he has a long year ahead of him, hopefully, and we want him bouncing into his races.
"If we give him time, I'm sure that will happen."
