Newcastle captain Kalyn Ponga hopes Connor Watson will be cleared to play in the grand final against his former club.
Ponga said Watson's injuries and adversity made him deserving of a place in his first decider, but his health must come first.
Watson's availability should be settled by Friday after two appointments with an independent neurologist on Thursday.
He was diagnosed with a category-one concussion after the Roosters' preliminary-final win over the Dolphins.
NRL rules automatically sideline category-one cases for 11 days.
The independent doctor initially classified Watson's concussion as category two, which carries no mandatory stand-down, before changing the ruling.
The Roosters are appealing the revised decision and hope to have the hooker available.
Coach Trent Robinson said Watson was fit, played several positions and had earned his place in the team.
"We want him to play, deserves to play, whether he is fit to play will get decided by somebody else, and then we will adapt."
Watson's potential appearance would be his last for the Roosters; he has agreed to join St George Illawarra in 2027 and Papua New Guinea's expansion team from 2028.
If Watson is ruled out, Robinson said reserve hooker Benaiah Ioelu would be considered after a strong season.
