La Bella Diosa will be out to resurrect her Sydney campaign on Saturday.
Connections of the leading New Zealand filly were on a high after her debut Australian victory in the group two Surround Stakes at Randwick, but they were brought down to earth with a thud by her next performance at Rosehill.
The daughter of So You Think failed to beat a runner home in the Coolmore Classic, after which a scope revealed a small amount of mucus. She was also suffering from mild lower airway inflammation.
"They were pretty minor issues to be fair and she's good now," said Matt Brown, whose wife and training partner Mandy is in Sydney with their New Zealand 1000 Guineas winner.
La Bella Diosa will now look to turn her form around in the group one Vinery Stud Stakes at Rosehill.
