Wests Tigers players will throw their faith in Robbie Farah to make the right call on his fitness for the do-or-die clash with Cronulla if given the all clear by surgeons.
Farah is in the race of his life to play in his Leichhardt farewell, having taken his fractured leg out of crutches and began running on a non-weight-bearing treadmill.
Tigers players have attempted to block the Farah situation out of their focus in recent weeks, refusing to let it distract their finals charge.
But they are well aware the veteran's bid to overcome a fractured leg bone suffered just three weeks ago will become a focal point headed into Sunday's clash.
There are plenty who believe Farah is highly unlike to figure in his Leichhardt swan song, which will double as his final NRL game if he plays and the Tigers lose.
But it wouldn't be the first time the hooker has overcome the odds to play.
He beat a dislocated elbow in just three weeks in 2014 to play in NSW's drought-breaking State of Origin series.
"I know how much he really wants to play and he will do anything to play," Benji Marshall, who knows Farah as well as anyone, said.
"But I know Robbie and if he feels like he can't give his best and it's going to affect the team then he won't.
"He's pretty unselfish like that but if he feels like he can do it, 100 per cent he will be in there."
Sunday's match is one of the biggest for the Tigers this decade, with the winner to advance to the finals and the loser's season set to be over.
The joint venture haven't featured in the finals since way back in 2011.
Farah will visit a surgeon early this week to get an opinion on his availability.
If he is any chance, he will be named in the Tigers' extended 21-man squad on Tuesday and then given until late in the week to prove his fitness.
The Tigers have lacked significant depth at the dummy-half position without Farah, with Marshall starting there in attack before Josh Reynolds comes on the field.
However Marshall said he had the issue firmly under control if Farah didn't return on time.
"I actually enjoy it (playing hooker). Apart from the sore back from bending over," Marshall said.
"Usually I am using my voice around where we go. When you are actually there at No.9 you just control it. It's up to me if we go left or right.
"The good thing for me is I can count numbers and implement our game plan.
"And then just let Luke (Brooks) just worry about what we do off the back of quick play the balls."
