“Reports received from the members of the international imaging panel who reviewed Durston’s CT scan results indicate that the horse is at heightened risk of injury.

“Acting on the specialist advice received from the international imaging panel, trainer Chris Waller has been informed by RV Veterinary Services that Durston is unsuitable to compete in the 2022 Lexus Melbourne Cup.

“Accordingly, Durston will not feature among the final acceptances for the Lexus Melbourne Cup when taken at 4.30pm (AEDT) on Saturday, 29 October 2022.”

Durston was on the fourth line of betting at $15 and has left champion jockey Damien Oliver without a ride in the Melbourne Cup.
