Jamayne Isaako can reach a landmark at Suncorp Stadium on Friday, needing only two points to score 300 this season.
That achievement would make him just the fourth player in rugby league history to reach the mark in one season.
Isaako's Dolphins host the Sydney Roosters in a sold-out Preliminary Final, with a maiden Grand Final appearance at stake.
The Dolphins have won their past eight matches at Suncorp Stadium and are pursuing a club-record ninth consecutive victory.
They also defeated the Roosters in both regular-season meetings this year.
Kristian Woolf has kept the 17 players who defeated the Warriors in Auckland in the Qualifying Final.
Tevita Naufahu drops into the extended reserves after being included in the 19-man squad last week.
The Roosters regain halfback Sam Walker following several weeks out with injury.
Daly Cherry-Evans returns to five-eighth, while Hugo Savala moves to the interchange and Toby Rodwell is omitted.
Egan Butcher is listed among the reserves after completing concussion protocols.
Interchange forwards Kurt Donoghoe and Connor Watson could shape the contest through their defensive work and ability to lift the pace.
Donoghoe will make his 55th NRL appearance, averaging 28 tackles per game this season.
Watson brings 192 NRL matches and averages 26 tackles in 2026, giving the Roosters valuable experience when fatigue arrives.
