Ryan Girdler is one of a growing number of former players and commentators saying Latrell Mitchell should have been sent off for his high shot on Joey Manu on Friday night.
Girdler also joined Mark Geyer in saying the Rabbitohs are no hope of winning the competition without Mitchell.
The Souths fullback will be suspended for at least six weeks after being hit with a grade two reckless high tackle charge by the judiciary.
The fullback must successfully have the charge overturned if he is to step foot on the footy field again in 2021.
The high shot is all anyone is talking about following South Sydney's 54-12 win over their arch-rivals at Suncorp Stadium.
Manu was forced off the pitch and taken to hospital immediately with a suspected fractured cheekbone.
Speaking on Triple M on Saturday, Girdler said Mitchell should have been sent off.
"How the NRL didn't send Latrell off last night has got me absolutely buggered," Girdler said.
"We saw what happened at Magic Round. Guys were getting a little tap or graze around the neck and we were having guys sent off and put in the bin.
"It was inadequate what happened last night.
"I know there's a few ex-players who've come out and said it's hard with the timing and that there's a lot of emotion in the game, but if the NRL is serious about getting these sorts of incidents out of the game, Latrell should've been marched immediately last night.
"He should've been gone."
Girdler continued, saying Mitchell's high shot was "selfish."
"There's parts of his game where he gets emotionally charged like that," he said.
"Whether it's grand finals or Origins, we've seen him have run-ins with certain players where he just needs to make sure he gets that team first mentality.
"Last night, what he did - to a degree - was all about Latrell.
"It was a selfish act and he's penalised not just himself, but the rest of that Souths side."
Rugby league hard man Geyer agreed that Mitchell should have been given his marching orders.
"I thought it was a send off. I thought no way is he going to see the rest of the game," MG said.
"It was the 57th minute, then he came back on and rubbed salt into the wound and scores a try in the 71st minute.
"That was a bad one. Was he aggressive? Yeah. I don't think he meant to injure Manu at all, they're good mates.
"That's not a good look. If that's not a send off, I don't know what is."
Both Girdler and Geyer agreed that the Bunnies can't win the premiership without Mitchell.
"There's been consequences for this one, with Joey Manu, who will miss the rest of the season, and his Roosters," Girdler said.
"Latrell's not going to play again this year, and South Sydney, I thought they were going to struggle to win the Premiership with him, but I don't think they can win it without him.
"It's a real shame, because two of the best players in the game at the moment aren't going to feature in the finals."
Said Geyer: "I think that's them done now. Latrell's been on fire this year on the footy field.
"He's been one of the top 10 players consistently in the competition this year.
"I don't think they can win the comp."
