Manly insist they've learned their lessons from playing without Tom Trbojevic with Brendan Elliot already feeling more confident in the No.1 if he has to replace him again.
The Sea Eagles are sweating on scans on their superstar fullback's left hamstring, after he limped from the field against South Sydney just two weeks into his return from the same injury.
The fact Trbojevic was completing a routine kick return and was untouched by any Rabbitohs defenders when he went down will be of great concern to not just the Sea Eagles, but NSW State of Origin officials.
Trbojevic is arguably as important to Manly as any player to any other club in the competition, after they lost their opening two games to the Wests Tigers and Sydney Roosters.
He sparked their season with two tries and two assists against the Warriors last week, and scored again on Saturday in the first half before limping off the field.
But Manly captain Daly Cherry-Evans, who admitted the injury left him feeling deflated, said that the Sea Eagles were able to fight back to win without him against Souths showed things could be different this time.
"We got in, we had a chat about it. We've learned some lessons from when Tom was out last time," Cherry-Evans said.
"I thought we adapted well, and the effort was there at the back end of the game to make up for Tom's workload.
"We've obviously got a class player out, but as a team playing a team sport, you've got to make sure your workload increases.
I'd like to think we're a smart enough team that we will be quite prepared for Tom's injury, but I hope it's not too long."
Manly could take a cautious approach with Trbojevic given the repeat nature of the injury.
They didn't rush him back following the pre-season blow, and the 22-year-old spent four weeks in recovery following that setback.
Elliot would be the man most likely to fill the No.1 void, after he also played there in the opening two rounds and looked more comfortable at fullback in the second half against Souths.
He also spent the opening two rounds playing in the rain, something that didn't suit the Sea Eagles up-tempo attack.
"You saw how great Turbo (Trbojevic) was last week, he's a class player and obviously this side is better with Turbo in it," Elliot said.
"I'm confident to slot into the fullback slot.
"The more games you get in a certain position the more confident you get. The second half just then as well, you grow into it a bit more again."
