Trainer Gerald Ryan has changed plans for Harper's Choice leading up to his Group One assignment.
Harper's Choice won the Premier's Cup Prelude (1800m) on August 11, beating Emperor's Way and Mighty Lucky who are both entered on Saturday.
“The plan is to go to Wyong with him instead,” Ryan said.
“He can't do both and the program fits in better for him with two weeks from the Wyong Cup to Newcastle and then two weeks to the Metropolitan.”
Harper's Choice finished second to Jon Snow in the 2017 Australian Derby but suffered with a high benchmark until this winter.
He won the Listed Winter Cup (2400m) on June 30 before his win in the Premier's Cup Prelude.
