Confirmed runners and riders for the Phoenix Stakes on Saturday as ante-post favourite Riber Tiber not declared

Ante-post favourite River Tiber is not one of seven declared for the Keeneland Phoenix Stakes (4.40) at the Curragh on Saturday, with trainer Aidan O'Brien expected to send his unbeaten juvenile to France for the Prix Morny on Sunday week.

The two-year-old stretched his winning run to three when denying Army Ethos by a neck in the Coventry Stakes at Royal Ascot, having also won at Navan and Naas on his two previous starts.

O'Brien will instead be represented by Unquestionable and His Majesty in this Group 1 contest as he bids for a record-extending 18th win in the race.

Unquestionable got off the mark at the second attempt over course and distance in May and will renew his rivalry with the Adrian Murray-trained Bucanero Fuerte, who prevailed when they met in the Group 2 Railway Stakes last month.

Owned by Amo Racing, Bucanero Fuerte, the mount of Kevin Stott, has won two of his three starts and finished third behind River Tiber in the Coventy. Amo will also be represented by Launch, who has yet to win in six starts.

Donnacha O'Brien has a strong hand in the first top-level juvenile race of the season as Albany Stakes heroine Porta Fortuna has been declared. The Caravaggio filly got off the mark over the minimum distance at this track in April, before landing back-to-back Group 3 contests. She will be ridden by Oisin Murphy.

Course-and-distance winner Givemethebeatboys and the Diego Dias-trained Gaenari complete the line-up.

Coral make Unquestionable the 9-4 favourite to hand Ballydoyle another victory in the race, with Bucanero Fuerte sitting just behind in second.

David Stevens, spokesperson for the firm, said: "With Unquestionable leading the Ballydoyle challenge for a race the yard has dominated for years, we have made him narrow favourite to reverse placings with Bucanero Fuerte from last month's Railway Stakes."
