Aaron Woods has been ruled out of the must-win game at Campbelltown Sports Stadium after being taken off with a knee injury against the Warriors.
Potter was disappointed with the loss of Woods but was confident that young players will step up to fill the void.
Woods unfortunately will not make the game, he has a slight knee problem, Potter said.
Im hoping he will be back within a fortnight.
Shaun Spence will come back into the side this week and will step up.
Potter urged Members and fans to show their support this week at Campbelltown, with Robbie Farah and Liam Fulton celebrating milestones.
We have a couple of big milestones with Robbie playing his 200th and Fulton with his 150th in a tough match against Manly, Potter said.
Its a big game coming up against the Sea Eagles, Id love to see you out there cheering us on.
We definitely need these two points and with you guys behind us it makes a big difference.
