North Queensland backrower Gavin Cooper will make his long-awaited Origin debut for the Maroons, slotting in for bench forward Josh Papalii (knee, shoulder).
Walters said he would mull over naming shadow players this week, with Canterbury?s Moses Mbye and Manly?s Daly Cherry-Evans the leading candidates.
But Walters said the game plan was to load up on an all-forwards bench at ANZ Stadium in a bid to seal a fifth series sweep for Queensland.
?I don?t think it is a risk, particularly in Sydney,? Walters said.
?NSW have got a dominant side and try to play through the middle. To combat that we have to make sure we are strong through there.?
