Josh Papalii has been rushed back into the fold after just a week's rest, with coach Ricky Stuart calling on his biggest trump card in a bid to halt an alarming four-match losing skid against Newcastle in Wagga Wagga on Saturday. The imposing front row enforcer missed last week's home loss to South Sydney after deciding with Stuart that he needed a 'mental break', but he's been named to start against the Knights with both clubs desperate to escape their dreadful form slumps. Papalii's return provides a huge boost to Stuart's forward pack which has struggled in recent weeks. In another boost for the Raiders, halfback George Williams has shaken the hamstring injury he suffered warming up against the Rabbitohs, while Sebastian Kris is also set to line up after being cleared of serious ankle damage. Homesick Williams' late withdrawal last Thursday was a massive blow for the Raiders, and forced Stuart into a late positional switch.
