"We've got to keep our guard up," Paasi said.
Whether or not Paasi plays a role in the match remains to be seen, with the veteran forward named on the extended bench. Warriors coach Stephen Kearney has named an unchanged 17, again giving promising young prop Jamayne Taunoa-Brown the start alongside Lachlan Burr, while Eliesa Katoa, Tohu Harris and Adam Blair fill out the back row.
However, there could be a change to the backline closer to game day, with dynamic back David Fusitu'a also named on the extended bench.
Fusitu'a has been out of action for the past three matches after remaining in Auckland for personal reasons when the team travelled to Australia before the restart of the campaign. As a result, he was forced to observe 14-day quarantine and has therefore been unavailable for selection until now.
Warriors squad to play the Rabbitohs: Roger Tuivasa-Sheck, Patrick Herbert, Peta Hiku, Gerard Beale, Adam Pompey, Kodi Nikorima, Blake Green, Jamayne Taunoa-Brown, Wayde Egan, Lachlan Burr, Eliesa Katoa, Tohu Harris, Adam Blair. Interchange (from): Karl Lawton, Poasa Faamausili, King Vuniyayawa, Jack Murchie, David Fusitu'a, Agnatius Paasi, Chanel Harris-Tavita, Isaiah Papali'i
