Prior was one of NSW’s best in Game II on debut and was strong from the outset.
Fittler however has gone another way pushing Paul Vaughan into the starting side with Sims in number 14.
Meanwhile, Daly Cherry-Evans returns to the Origin arena replacing the under siege Ben Hunt for the dead rubber.
Billy Slater will captain the side from fullback in his final ever Origin appearance.
