Sydney Roosters host Dolphins at Allianz Stadium in Round 26 with both clubs occupying top-four positions on the NRL ladder after 21 games. Roosters hold the minor premiership edge through superior points differential and home-ground consistency, while Dolphins maintain strong attacking output led by halfback Isaiya Katoa and a settled forward pack despite earlier-season Origin absences. The sides split results in prior encounters, including Dolphins’ dominant June victory when multiple Roosters players were unavailable. Recent form, travel considerations for the visitors, and potential late-season rotation or injury management create the narrow market balance, with any confirmed team lists or weather updates likely shifting implied probabilities before kickoff.
