The two-time Group 1 winner has been unplaced in her last two runs and trainer Mark Walker says she will have an extensive check-up.
"But she definitely won't race again this spring and if she races again in the next few months it will likely be fresh-up in the Railway [January 1]," says Walker.
Karaka Million winner Dynastic will head the Sarten Memorial at Te Rapa on Saturday. His 2000 Guineas campaign needs to get back on track after racing well below his best in the Hawke's Bay Guineas.
● Kiwi trainer Andrew Forsman finds himself in a scarcely believable position after his Caulfield treble.
The wins of Saint Bathans, Mr Maestro and Aegon on Saturday take him to sixth on the Victorian trainers Metro premiership, with seven winners from just 12 starters.
The trainers above him in the metro premiership are all local legends and average 79 metro starters this season. Directly below him, all with a lot more starters, are expat Kiwis Chris Waller, Patrick Payne and Mike Moroney.
Forsman has Mr Maestro as the $3.50 favourite for the Victoria Derby on October 29.
