The outcome of a medical appointment will determine whether Tye Angland can ride first starter To Excess at Randwick.
Angland needs a medical clearance to participate in Saturday's meeting after he was injured at the track a week ago.
The jockey slipped a disc in his back during the running of the second race and was stood down from his remaining rides.
He has undergone physiotherapy treatment this week and will consult his doctor on Friday when he is hoping to be given the all clear to return to the saddle.
Because of the confusion over his fitness, Angland's only booking for Saturday's Randwick meeting is the Tracey Bartley-trained To Excess in the TAB More Than Just Winning Plate.
Angland has partnered the youngster in two barrier trials and says he has enough natural gate speed to overcome a wide barrier.
The Listed Carrington Stakes is the feature race at Randwick, attracting a field of seven starters.
In-form Godolphin galloper Medcaut is favourite ahead of the resuming You'll Never from the Chris Waller stable.
