Walker facing ban over elbow in fiery clash with Dogs

South Sydney pivot Cody Walker has been hit with a grade one striking charge for an elbow to the back of Nick Meaney's head that takes the gloss off a blistering one-two combination with Damien Cook in Friday's 38-0 win over the Bulldogs.

Walker could not recall the first-half incident that Mal Meninga described as "deliberate" in Fox Sports commentary.

Meaney was being brought to ground by a Rabbitohs teammate when Walker joined in the tackle, falling onto the Bulldogs fullback with a cocked forearm that collected him in the back of the head.

"You could see that was deliberate," Meninga said before referencing the dangerous contact Felise Kaufusi made in knocking out Eels back-rower Ryan Matterson two weeks ago.

"We talk about [Melbourne's] Felise Kaufusi and his two weeks suspended for a deliberate elbow to the back of the head [against Parramatta], I think he's in some serious trouble."

Walker is set to miss one match after being charged with grade one striking, and risks a two-match ban if he challenges the ban at the judiciary and loses.

He was involved in plenty good and bad throughout the 38-0 drubbing of Canterbury, scoring two tries and taking centre stage in a second-half melee as well.

A clip of Walker stepping on Corey Waddell's ankle early in the contest as he waited at dummy half also did the rounds on social media after full-time, while teammate Keaon Koloamatangi is facing a two-match ban for a crusher tackle on Will Hopoate.

Coach Wayne Bennett said he didn't see the Meaney incident, but joked that he would be checking his five-eighth's medication because "there was obviously something going on, he had the angry pills in today".

Walker could only laugh at Bennett's analysis and said any tension surfaced only in the heat of battle and wasn't premeditated.

"I can't remember that incident [with Meaney], but in any game you're trying to win a game of footy and what happens on the field stays on the field I suppose," Walker said.

"We shook hands after the game and that's where it will stay.

"It's just spur of the moment, it's a big occasion here on Good Friday at Stadium Australia, a massive crowd and the Dogs a very gritty side.

"Every time we've played against them they're a hard team to break down. They showed in the first half they're a hard team to break down.

"A lot of the tries didn't really come from shape, it was Cookie running through the middle."

Cook's running game came to the fore at the Olympic stadium, carving through the middle twice for Walker to score two tries in support.

The NSW and Test No.9 has been criticised at times for not taking on the line enough, but Walker said Cook's running game remained one of South Sydney's greatest points of difference against their rivals.

The hardest part for Walker is keeping up with his hooker when he puts on the afterburners.

"There's a few different cues that I look for," Walker said.

"I'm obviously not going to give them away, but I understand when he's about to jump and go. My job is just to try and keep up with him because he's so quick.

"When I scored the first try he had to sort of lob it up to me because I was still a bit away from him. It's a combination that we've grown over the last couple of years."
