The Dolphins will face the Sydney Roosters at Suncorp Stadium on Friday night for a place in their first NRL Grand Final.
The Brisbane club earned its preliminary-final opportunity by defeating the Warriors across the Tasman in the qualifying final.
A subsequent week off has given the Dolphins time to recover before returning to a sold-out Suncorp Stadium.
Head Coach Kristian Woolf has retained the same 17 players who secured that victory.
Felise Kaufusi is listed as the 18th player, with Brad Schneider named 19th.
Jake Averillo, Brian Pouniu and Tevita Naufahu complete the extended squad for the decisive match.
