Trainer Adam Trinder has advised Racing Victoria (RV) Stewards that Mystic Journey has a soft tissue infection in the left front limb.
The four-year-old mare is currently undergoing veterinary treatment and as a result will miss several days of track work.
The only current nomination held by Mystic Journey is for the All-Star Mile to be run on Saturday, 14 March at Caulfield.
With voting for the All-Star Mile opening to the public tomorrow, Mr Trinder advised the Stewards of the injury, so that everyone is fully informed.
