Rock Of Gibraltar, who takes a streak of seven straight Group I victories into the Breeders' Cup, and Hawk Wing have both been put in the Mile and the Classic.

O'Brien signaled his likely plans by nominating the Mile as Rock Of Gibraltar's first preference, with the Classic being Hawk Wing's preferred objective.

``But that doesn't mean the situation cannot change,'' the trainer said.

Irish and English Derby winner High Chaparral, third in the Prix de l'Arc de Triomphe recently, is named to the Turf.

O'Brien has entered five for the Juvenile, a race he won last year with Johannesburg. The 2-year-olds – Hold That Tiger, winner of the Grand Criterium, Tomahawk, Van Nistelrooy, Ontario and Marino Marini – were also entered in the Darley Dewhurst Stakes at Newmarket on Saturday.

``A lot of other things will have to be taken into consideration before we finalize plans for the Juvenile,'' he said.

Also entered by O'Brien is Shadwell Mile (gr. IT) winner Landseer in the Mile and Reach For The Moon, who finished third in the Meon Valley Studs Fillies' Mile at Ascot last month, for the Juvenile Fillies.
