Leading Queensland jockey Michael Cahill has a fractured foot but will have further tests before it is determined how long he will be out of the saddle.
Cahill was the star of the winter carnival winning two Group One races and started the new season in fine form to be second on the metropolitan premiership with 19 winners.
He withdrew halfway through the Sunshine Coast meeting on Friday night sand was not fit to ride at Eagle Farm on Saturday.
Cahill visited a doctor on Saturday morning and an X-ray confirmed he had a fracture high up on his right foot.
