The Dolphins reached their strongest season since entering the NRL in 2023, but now face difficult decisions over several key players.
Tom Flegler's future is unresolved as the club works through its roster plans ahead of the November 1 deadline.
Players without contracts for 2028 can negotiate with rival clubs after this week, leaving the Dolphins vulnerable if Flegler remains unsigned.
The 27-year-old prop is a Queensland Maroons representative and one of the game's leading front-rowers, qualities likely to attract rival interest.
After missing almost two years with a complex nerve and shoulder problem, Flegler returned to the NRL and played 21 games last season.
He recorded 96 per cent tackle efficiency in the Dolphins' forward pack.
The club has retained Selwyn Cobbo while he is in career-best form, and the Daily Telegraph reported Wednesday that Hamiso Tabuai-Fidow had signed a long-term deal.
Herbie Farnworth and Jack Bostock, both off-contract at the end of 2027, also have uncertain futures.
