Sunbury is all but out of the promotion race in state league division 3 north-west after a 3-3 draw with relegated Essendon United at the weekend.
Match postponements due to the weather mean Sunbury will go into the final round still within two points off second place on the ladder.
But unfavourable results when teams with games in hand play could drop United to as low as seventh on the ladder.
Sunbury finishes its season with Lalor this weekend at Langama Park; kick-off is 3pm.
