Four apprentice jockeys have been taken to hospital following a multiple horse fall at Taree but all appear to have escaped serious injury.
Samantha Clenton's mount Bazza's Boy came down at the home turn of Monday's first race with his rider suffering a suspected broken collarbone and leg injuries.
Blinkin Rules, ridden by Jackson Murphy and Casino Bride with Nyssa Burrells aboard both fell over the top of the stricken horse.
Lady Lobbaan (Kaylee Kirkwood) and Nonino (Taylor Marshall) were badly interfered with and both riders came off.
Kirkwood and Murphy have suspected leg injuries while Burrells will also have scans.
Marshall has a slight concussion and will be stood down for the rest of the day.
