Bryce Stanaway's stayer Cliff's Dream was put down after a jumps fall on Tuesday, ending the Warrnambool Carnival's five years without a death.
The seven-year-old grey gelding fell on the inside of a tightly bunched field at the second-last hurdle of the 3200m George Taylor Memorial Hurdle and fractured hisnearside knee.
A green screen was pulled around the horse on the final bend before he was euthanized.
Jockey Richard Eynon fell over the falling gallopers neck and took some time to sit up but after being attended by ambulance officers was able to walk back to jockey's room.
Stanaway comforted the visibly upset Eynon and said the fall was "no one's fault, that's racing".
The Torquay trainer had moments earlier watched a replay of the race in the stewards room and sadly shook his head when he saw Cliff's Dream come down.
He said it did not look like a serious fall.
"It's no one's fault, it was just one of those accidents," he said.
