Starcraft is set to contest the Breeders' Cup Classic race at Belmont Park on Saturday despite doubts over his run after an administrative row.
Starcraft has been drawn in stall 14
Australian owner Paul Makin had said a dispute over the licensing of the ownership syndicate could threaten the participation of the five-year-old.
But Makin later said he was "just letting off steam."
He paid a supplementary fee of $800,000 (£450,000) for the Queen Elizabeth II Stakes winner to enter the race.
Starcraft cantered again on the dirt track and has pleased Newmarket trainer Luca Cumani since his flight over from Britain.
"He looks good and we're happy," the trainer said. "The 14 draw is not going to be a big help for him but if he takes to the surface he might just do it."
Meanwhile, star British filly Ouija Board worked on the track's rain-softened turf surface.
