Not seen since winning the Dewhurst as a juvenile, Jim Bolger’s colt in also in the mix for the Investec Derby.
Aidan O’Brien, looking for his fourth Irish 2000 Guineas win in five years, will field four runners – Power, Wrote, Daddy Long Legs and Reply.
John Oxx has two live chances with Takar, the mount of Johnny Murtagh, and Sea The Stars’ half-brother Born To Sea, who will be ridden by Pat Smullen.
The Richard Hannon-trained Trumpet Major will be joined by Bryan Smart’s Foxtrot Romeo as the only two British challengers.
Hermival, third in the Newmarket equivalent, will travel over from France.
Alkazim, trained by David Wachman, completes the field.
Meanwhile, Aidan O’Brien is happy with Investec Derby hot favourite Camelot.
He said of Camelot: “He has been good (since winning the Qipco 2000 Guineas) - everything is fine.
“He has been going gently and everything is well so far. I am happy with him.
“He has always been a very special horse here, from day one. He was a very short-priced favourite when he went for his maiden and then I was very happy with him in the Racing Post Trophy. His first big test was the Guineas.
“He is one of those very special horses. He is very relaxed, very straightforward and very calm but has a lot of nervous energy.”
Referring to his other entries, Astrology, Imperial Monarch, Father Of Science and Tower Rock, O’Brien said: “All the others are on Derby work regimes and everything has gone well so far. They will go through all the tests next week and we will decide what to do.”
Turning to the same afternoon’s Diamond Jubilee Coronation Cup, O’Brien said: “Hopefully, Joseph (O’Brien) will ride St Nicholas Abbey. That is the plan anyway. He is definitely the main runner we will have there.”
Hayley Turner is set to partner Cavaleiro in the Investec Derby at Epsom next Saturday.
While Turner plundered two Group Ones last term, landing the July Cup on Dream Ahead and the Nunthorpe on Margot Did, she has yet to line up in the premier Classic.
However, Turner will break new ground when she is given the leg up aboard Marcus Tregoning’s charge next weekend.
Alex Greaves is the only woman to have previously ridden in the Derby, finishing last on Portuguese Lil in 1996.
