In an ominous warning for Saturday's rivals if she does run, Coleman said Sigh had come on from the last-start win over General Beau and Zac De Boss, which was her second straight win this campaign at Saturday's venue.
"She had to really tough it out, which was nice to see, and she looks even better now than what she did leading into that run," Coleman said.
"She's got the best coat in the stable. She's absolutely glowing."
Carleen Hefel retains the ride on Sigh, who has drawn barrier six, a new rider will be required for Invincible Caviar with Linda Meech ruled out due to injury and Will Price has the job aboard Dance To Dubai.
