Glyn Schofield is the new rider for George Main Stakes favourite Kermadec, replacing the suspended Glen Boss.
The Chris Waller stable confirmed the booking on Wednesday after Boss lost his appeal against the severity of a careless riding suspension.
Doncaster Mile winner Kermadec will be one of three runners for Waller in the Group One Randwick feature along with Royal Descent, to be ridden by Hugh Bowman, and Moriarty for Jim Cassidy.
