Apprentice Deanne Panya has been cleared of throat damage but has a broken collarbone and cuts to her face from a fall at Rosehill.
Panya came off Sebring Express around the 250m-mark in the Widden Stakes on Saturday and was unconscious for a short time.
Racing NSW doctor David Duckworth said Panya had a deep laceration to her chin and a decision would be made on Monday whether she needed further treatment on her collarbone.
Her injuries mean Panya will miss the ride on Sebring Express's Gary Portelli-trained stablemate Testashadow at Randwick on Saturday.
The jockey scored her biggest win when she rode Testashadow to win the $1 million Magic Millions Cup at the Gold Coast on January 14.
Testashadow is scheduled to run in a 1600m-benchmark race at Randwick.
