Rebeka Prest will spend at least the next six weeks in a back brace after a nasty fall at Murrumbidgee Turf Club on Saturday.
Prest fractured her T12 vertebrae after being dislodged from White Emperor.
The Kerry Weir-trained gelding blundered at around the 800 metres, dislodging Prest before continuing on riderless.
With the fracture stable Prest doesn't require surgery, but remains at Wagga Base Hospital awaiting further medial advice.
Meanwhile Tyler Schiller continued his recent good run with a treble at the popular Christmas Party meeting.
After a double at Hay last Saturday, and more success at Wodonga on Friday, the apprentice jockey combined with David Blundell to win the opening race with Only A Dream.
He then rode Bid Of Faith to victory for Doug Gorrell before capping off the meeting with Jungle Book for Trevor Sutherland.
Sutherland continues to be impressed.
"He's an outstanding young kid," Sutherland said.
"He's just starting to get a little confidence in his own ability now and will just grow in leaps and bounds."
Jungle Book was part of a winning double for the Wagga trainer, who also had Azaryah make it back-to-back wins after almost two years off the track.
Sutherland is thrilled with the mare on the comeback trail from a tendon injury.
He's weighing up a trip to Rosehill with her on Saturday with Two Wrongs Dont in another Highway Handicap.
