Rabbitohs star Cody Walker has been handed a two-match suspension over his involvement in a Casino street fight late last year. South Sydney have been issued a $20,000 fine after they failed to inform the NRL of the incident, which Walker reported to coach Wayne Bennett shortly after it happened.
Walker, who was also given a $15,000 suspended fine, will miss crucial clashes against Sydney Roosters and Melbourne Storm.
The club has five days to appeal or accept the $20,000 fine.
"All clubs and club officials have a duty to report any incident which may lead to a breach of NRL rules, including suspected breaches, and NRL clubs are responsible for ensuring compliance," the NRL said.
The NRL Integrity Unit handed down the decision just two days after he Police cleared Walker of any charges stemming from the incident.
Footage of Walker fly-kicking another male from last year surfaced online on Monday after he informed police he'd been asked for $20,000 in an extortion attempt.
In the footage Walker can be seen kicking a man in the chest during an altercation. Speaking to the media on Monday, he apologized and claimed he was emotional after grieving the death of his cousin.
"It was not a true reflection of my character and who I am as a person," Walker said.
An investigation into the brawl and the extortion attempt was opened by detectives earlier this week. Investigations into the fight have since concluded with Walker cleared of any charges, while two men aged 20 and 21 have been issued criminal infringement notices for offensive behaviour.
It's alleged the extortion attempt took place on Saturday when someone called Walker's agent Matt Rose demanding cash.
Detectives have traced the number back to another player agent, who is now under investigation.
