Regan Bayliss faces an extended break from the saddle after breaking his wrist in a race fall at Geelong on Friday.
Bayliss was riding the Lindsay Park trained debutant Amschel when the two-year-old colt clipped heels and fell at the 900m mark of the 1112m race.
Both Bayliss and Dean Holland, rider of Wanna Be Good, were dislodged from the saddle during the incident but while Holland escaped unharmed and was able to continue riding at the meeting, Bayliss was transported to Geelong Hospital for x-rays.
Jockeys Association boss Des O'Keeffe confirmed that Bayliss' wrist was the main area of concern following the fall, with doctors identifying a break on inspection of x-rays.
Bayliss' brother and fellow jockey Jake took to Twitter at 5:30pm to deliver the news that his brother would be required to stay overnight at Geelong hospital and that he may require surgery to repair the wrist.
Further assessment over the weekend would determine the course of action.
The fall comes in the same week that Bayliss achieved a career best five winners at the Geelong synthetic track, which he has held a remarkable winning strike rate at this season.
Bayliss will be replaced for his rides at Morphettville on Saturday where he was to partner the Lindsay Park trained Faatinah in the G1 Darley Goodwood as well as three other rides in stakes races.
