The Gai Waterhouse-trained Najoom will have to rely on two scratchings to make the field for the Tattersall's Tiara at the Gold Coast, the final Group One race of the season.
The highly fancied filly is the second emergency with 16 to run on Saturday.
The early favourite for the Stradbroke Handicap, Najoom missed that race with a minor leg injury.
Stradbroke winner Srikandi heads the Tatt's Tiara field which is determined by prize money earned.
