The Tigers left-edge defence is in for an uncomfortable video review session after all four of South Sydney's tries in an 18-10 win came by targeting co-captain Moses Mbye and halfback Luke Brooks.
Winger Reece Hoffman was a late call-up for fellow youngster Tommy Talau, who twinged a hamstring during Thursday's captains' run and is expected to be available again for a round nine clash with Brisbane.
Hoffman was given a torrid time marking up on Queensland Origin veteran Dane Gagai, who finished with the first hat-trick of his NRL career as the Rabbitohs repeatedly exposed Hoffman's inside defenders.
The 19-year-old hit back late with a try on debut but in each of the four South Sydney tries he was left carrying the can for poor reads by either Brooks or Mbye.
"They put us under some pressure," coach Michael Maguire said afterwards.
Match Highlights: Rabbitohs v Wests Tigers
"At times there young Reece, I thought he actually played well but obviously he had some attacking raids going to his side.
"But I think there was a fair bit going on on the inside that affected what was going on on the outside, so we'll have a look at that as well."
Benji Marshall was injected into the contest midway through the second half and the Tigers fightback began in earnest with him steering the ship.
While Josh Reynolds faces a nervous wait after he was placed on report for kicking Campbell Graham, Maguire has a selection headache on his hands regardless given Marshall's impressive return.
Immortal halfback Andrew Johns was adamant on Channel Nine after fulltime that Marshall should be back in the halves against Brisbane.
"Benji has to be there next week," Johns declared.
Welcome to the NRL, Reece Hoffman
"He has to be in the six jersey. He had some beautiful touches didn't he late in that game."
The Tigers coach was pleased with Marshall's contribution and his ability "to help us steer the back end of the game.
"It's something that's been probably lacking over the last couple of weeks but it wasn't to be."
Maguire also plans to raise a contentious Rabbitohs captain's challenge with NRL officials after a high shot by Jaydn Su'A was overturned – after Souths players were able to watch a replay on the Bankwest Stadium big screen.
Challenges are meant to be lodged with the referees within 10 seconds but this one came after a lengthy delay.
"I'll be talking to the powers-that-be about that one,'' Maguire said.
"Obviously time lapses and there was a fairly long period of time between the time when you should be doing the captains challenge, so I'll be checking in about that one."
