Champion sprinter Chautauqua is among 10 horses entered against Winx as she attempts to extend her winning streak to 16 in the George Ryder Stakes at Rosehill.
Darren Weir has nominated the Futurity Stakes quinella of Black Heart Bart and Tosen Stardom while Le Romain, who nosed out Chautauqua in the Canterbury Stakes is also among the entries.
Hartnell, second to Winx in the Apollo Stakes before his Chipping Norton failure, is scheduled to run in the Ranvet Stakes, one of five Group One races on Saturday's Golden Slipper program.
The field and barrier draw for the Slipper will be declared on Tuesday with all other races finalised a day later.
