Sky Lantern and Just The Judge remain on course for a mouthwatering rematch in the Coronation Stakes at Royal Ascot but Michael Stoute's hugely impressive York scorer, Pavlosk, has been supplemented at a cost of £25,000 and is among the 19 confirmations.
Richard Hannon's Sky Lantern narrowly beat the Charlie Hills-trained Just The Judge when claiming the 1000 Guineas at Newmarket in early May, but the latter has since turned in an impressive triumph in the Irish equivalent.
The pair look set to once again lock horns in Friday's Group One feature, while Hannon could be double-handed with the talented Maureen.
Aidan O'Brien has three possible runners in Hanky Panky, Magical Dream and Snow Queen.
Eddie Lynam's Viztoria and the Dermot Weld-trained Big Break are other major contenders for the Irish raiding party.
Other possible runners include William Muir's Purr Along and French hopefuls Kenhope and Siyenica, but the Lady Cecil-trained Hot Snap has been taken out of the reckoning.
