Saturday night's clash at the SCG will go a long way towards deciding whether the Knights will be a force in the finals.
If they're able to prove themselves against the back-to-back premiers they will enter the post-season knowing a deep run is possible. A meek showing will undo all the good work they achieved in the win over Cronulla last weekend.
As for the Roosters, the troops have returned and sights are set on having everything clicking when the finals begin.
Match: Roosters v Knights
Round 18 -
Venue: Sydney Cricket Ground, Sydney
Roosters: Jared Wearea-Hargreaves is out of the Roosters team, with Isaac Liu moving from lock to prop and Angus Crichton elevated to the starting side. Lindsay Collins will play off the bench.
Skipper Boyd Cordner has returned to the Roosters COVID-19 bubble and took part in Friday's captain's run after being granted an NRL exemption from biosecurity protocols on family grounds. Cordner travelled to Newcastle during the week after his cousin underwent emergency brain surgery following a head knock playing in the local first-grade competition. Tragically, his cousin, Joel Dark, died on Friday, aged 19.
Jake Friend returns at hooker in place of Freddy Lussick in the only change from last week's win over Canberra. Retiring club great Mitchell Aubusson has been moved up from the reserves to the interchange bench.
Lussick and Poasa Faamausili were omitted from the reserves an hour before kick-off, while Ryan Hall and Hargreaves were the two players left out 24 hours before the match.
Knights: Kalyn Ponga, Mitch Barnett and Hymel Hunt have been rested with Tex Hoy at fullback and Edrick Lee back from injury on the wing. Daniel Saifiti will start at prop, with Jacob Saifiti moving to lock and Herman Ese'Ese dropping to the bench. Sione Mata'utia (ankle) and Chris Randall are also on the bench after initially being named as reserves.
Pasami Saulo and Tautau Moga were trimmed from the squad an hour prior to kick-off, while Phoenix Crossland and Brodie Jones were the two players omitted 24 hours before the match.
The Knights have lost three and drawn one against top-four opponents this season.

Jared Waerea-Hargreaves v David Klemmer. It's always fun when two of the biggest, meanest and best forwards in the Telstra Premiership run into each other. Both men have plenty of help in their respective forward packs, but their battle remains a key contest.
Between them, James Tedesco and Kalyn Ponga combined for five tries, 456 running metres and five line breaks last weekend. Unfortunately Ponga's absence means the fans won't get to see two of the game's most electrifying players trying to out-do each other.
