A DRAMATIC fall at the Country Championships saw four jockeys hospitalised and two horses died.
Jockey Greg Ryan and horse Son Of A Dun hit the decks when it collapsed at the 900 metre mark.
The domino-effect saw Josh Adams, Rachel King, Kath Bell-Pitomac and Wendy Peel take the fall along with Ryan.
Five jockeys were reportedly hospitalised, but a NSW Ambulance spokeswoman said only four riders were taken to Tamworth hospital.
Races were delayed for the day as ambulances tended to the injured.
It's believed Son Of A Dun, ridden by Greg Ryan suffered a heart attack and collapsed in race two at the Country Championships qualifier meeting on Sunday.
The fall resulted in a domino effect that forced the other riders out of the saddle.
The incident "subdued spirits" at the course, Tamworth Jockey Club interim chairman Wade Berryman said.
"No one likes to see horses fall, let alone have to be euthanised," he said.
"Certainly no one wants to see jockeys injured."
All jockeys remained conscious after the fall and none had life-threatening injuries.
The rest of the races were delayed by 40 minutes while paramedics tended to the incident.
There were around 1000 people on the course on Sunday, the club had hoped for 1500.
