"He worked well on Wednesday night. Everyone was very pleased with him. He pulled out a bit of speed which is what they wanted."
Chester Vase winner Doctor Fremantle, trained by Sir Michael Stoute, is another expected to be added to the field.
"At this moment he is going to be supplemented," said Teddy Grimthorpe, racing manager to owner Khalid Abdullah.
