Doctors will slowly bring New Zealand jockey Michael Walker out of sedation as the star rider continues to make positive progress after a fall in Victoria on Monday.
Walker, who lives in Victoria, was riding in a jumpout at Pakenham on Monday morning when the horse collapsed.
The 38-year-old was treated by paramedics before being transported to the Alfred Hospital by helicopter.
Walker suffered serious head trauma following the fall and was placed in an induced coma.
Initial scans on Monday afternoon cleared Walker of internal injuries and spinal damage.
