Sydney Roosters captain James Tedesco and halfback Daly Cherry-Evans missed Monday's training because of illness, but coach Trent Robinson expects both to play.
"A little bit crook, but that's cool. That's the life of an athlete," Robinson said.
The major selection news is Sam Walker's return from ankle surgery for Saturday's preliminary final against the Dolphins.
Walker targeted a week-three finals comeback only days after surgery, surprising Robinson with his physical recovery and commitment.
"He's 100 per cent," the coach said.
Walker is expected to play the full 80 minutes and reclaim goal-kicking duties from Hugo Savala.
Savala moves to the six-man bench after filling in effectively at five-eighth during Walker's three-week absence.
"Hugo is so important to the team and the way that he approaches the game and plays the game and he'll have his part to play," Robinson said.
Robinson dismissed suggestions Savala could replace Billy Smith at left centre, saying, "Billy's the definite left centre."
He also said Tedesco and Cherry-Evans should complete substantial training before the match.
