Much hangs on this match-up of premiership hopefuls hoping to bounce back from demoralising round 11 thumpings.
Hosts South Sydney face the bigger challenge having coughed up 50-plus points to competition front-runners Penrith and Melbourne in heavy round nine and 11 losses.
The fact that the Rabbitohs' only defeats of 2021 have come at the hands of their main rivals for a spot in the grand final will be especially concerning for coach Bennett.
The good news is that not only do they have one of the best coaches in NRL history to plot their comeback but they also boast one of the competition's most potent backlines.
Parramatta can take solace in the fact that their upset 28-6 loss to arch-rivals Manly appears, at this stage at least, to be more of a blip than an indication of deeper problems.
Match: Rabbitohs v Eels
Round 12 -
Venue: Stadium Australia, Sydney
Rabbitohs: Cameron Murray (ankle) and Jacob Host (quad) will make their returns, with Liam Knight and Jaydn Su'A relegated from the side humbled by Penrith.
Murray moves to an edge forward role with Mark Nicolls starting at lock and Host to come off the bench.
Josh Mansour (head knock) will miss this week's game and his place on the wing is taken by Taane Milne.
Jai Arrow has been promoted to start at prop with Thomas Burgess going to the bench. Hame Sele joins the bench and Jed Cartwright misses out.
Su'A is the 18th man with Braidon Burns dropping off the extended bench an hour before kick-off. Knight and Patrick Mago were the first two players cut from the extended squad 24 hours before kick-off.
Eels: Prop Reagan Campbell-Gillard took an early plea on a high tackle charge and will miss this weekend's game. Oregon Kaufusi moves into the starting side and Marata Niukore joins the bench in his comeback game from a two-week suspension.
Will Penisini is the 18th man with Makahesi Makatoa dropping off the reserves list on game day. Haze Dunster and Jordan Rankin were the first two players omitted from the extended squad on Friday.
Five-eighth Dylan Brown has another week of his ban to serve. Utility Will Smith (thumb) is likely at least another week away from a return.

Damien Cook v Reed Mahoney: With Harry Grant a real chance of missing Origin I, is this a dress rehearsal for the clash between the NSW and Queensland No.9s? It appears only injury will stop Cook from being named while Mahoney is now a great chance of getting the nod for the Maroons.
It's all about eliminating the negatives for South Sydney and Parramatta. Both rank in the top five for ineffective tackles (Eels No.2 - 203, Rabbitohs No.5 - 195) and top 10 for handling errors (Eels 4th - 106, Bunnies 7th - 103). Souths are also top 10 for penalties conceded (7th, 43) but Parramatta clearly have the upper hand here as only Newcastle (35) have conceded fewer than the Eels (37).
