It'll be the Newcastle Knights or the Penrith Panthers advancing to the 2018 Jersey Flegg Grand Final after Saturday's game.
The club's face-off this weekend for a place in the big dance in a rivalry three years in the making.
"They're quite a good defensive team, they're big, strong, run the ball hard. They're also quite a good defensive team," Knights 20s coach Todd Lowrie said.
"Our guys have had a bit of a running battle with this team.
"The boys told me through their junior careers, the 16s and 18s, they've played against each other in quite a few big games. Once we knew we were playing Penrith, the guys were pretty excited because they have some scores to settle."
Lowrie's men are just one win away from the 2018 grand final in a year where his team won the minor premiership.
With plenty at stake, Lowrie is confident his troops have their nerves in check and has been preaching that his men enjoy what is left of the rugby league season.
"This time of the year, the guys are excited and motivated," Lowrie said.
"I don't have to do any of that. As long as we are clear on what we need to do at training and prepare well, the excitement of the occasion and what's at stake is certainly enough to get the guys up.
"We're pretty relaxed. It's about enjoying the games. I remind the boys to enjoy the session and get the most out of it because there's only three other teams preparing this week."
