Aidan O'Brien will saddle Camelot and Learn as he bids to win the Racing Post Trophy for a sixth time at Doncaster on Saturday.
The Ballydoyle trainer has taken out Royal Lodge winner Daddy Long Legs and Tibet and will just be double-handed in the final Group One of the season in Britain.
Camelot has headed the ante-post market despite having had only the one run at Leopardstown, a win in July, under his belt, while Learn's only win from three starts also came at the same venue.
Camelot is currently favourite for the 2012 Derby at Epsom.
There is a third Irish challenger in the shape of Jim Bolger's Zip Top, who was third to Crius in the Tattersall Stakes at Newmarket last time out. He was supplemented for the race on Monday.
Godolphin rely on impressive Newmarket maiden winner Encke from Mahmood Al Zarooni's stable, another supplementary entry, while the John Gosden-trained Fencing and Jeremy Noseda's Talwar complete the line-up.
The only other withdrawal at the 48-hour final declaration stage was the Roger Varian-trained Farraaj.
