The last race at Doomben has been abandoned after jockeys voiced concern about visibility in overcast conditions.
The riders agreed to take part in the second last race of the day, the Bottle-O Class 6 Handicap at 4 pm, because the field was small.
With four horses scratched, only six runners took part.
However stewards called the jockeys in before the last and they said there were concerns because of the 14 runners in the field.
The TAB Qtis Handicap for three-year-olds initially listed 16 runners, with two of them later scratched.
Chief steward Peter Chadwick said stewards agreed with the riders and had decided to abandon the final race due to issues with visibility and ongoing rain.
