The Magpies have elected to go in with the same side that enjoyed a 41-point win over Sydney last weekend.
John McCarthy, Steele Sidebottom and Tyson Goldsack have all been named as emergencies.
The Bulldogs have made one change regaining the services of star midfielder Daniel Cross for Dylan Addison.
The Magpies will enter the final round placed third, one game and three percentage points ahead of the fourth-placed Dogs. They would have to be beaten by 22 points or more to drop to fourth place.
