A gallop by Americain at Caulfield on Saturday morning will decide whether he starts in Saturday week's Caulfield Cup.
If he gets the all-clear, he will be one of at least four international runners, alongside Dunaden, Quest For Peace and Jakkalberry.
Trying to join them will be John Gosden-trained Gatewood and Alain de Royer Dupre's Shahwardi, who would have to win the ballot-exempt 2400m Herbert Power Stakes at Caulfield on Saturday.
Ibicenco, trained by Luca Cumani, also may run in the Herbert Power.
Godolphin has selected Lost In The Moment and Cavalryman as its spring carnival representatives and the horses have gone into quarantine.
