Melbourne Storm second-rower Shawn Blore, 25, pleaded guilty to common assault stemming from a July 2024 melee involving his brother in Sydney's city centre.
Another man, Naaman Mikhael, had been asked to leave the Little Hunter Street restaurant for being aggressive and making threats towards the venue owner, Downing Centre Local Court was told on Friday.
Blore and his older brother Dean were also leaving the premises with a group of friends when the owner heard Mikhael "mouthing off" at Dean's partner.
A heated exchange between Mikhael and Dean followed, resulting in a physical confrontation in which Blore's brother pinned the 31-year-old's back against a wall.
The Storm forward attempted to break up the scuffle between the pair, while several other unrelated skirmishes took place around the group.
CCTV footage of the incident showed "multiple skirmishes between different groups of people" taking place outside the restaurant, the court previously heard.
The Storm second-rower and his brother were initially charged with affray, which they denied, before pleading guilty to the lesser charge of assault.
Sparing each brother a conviction, magistrate Christine Haskett said she was confident the incident was unlikely to happen again.
"And if it does, hopefully you can disassociate yourselves," she told the brothers.
The Blores were both placed on six-month, good behaviour bonds, a sentence used for first-time and less serious offences.
Mikhael was also previously charged with affray, but he had his charge dismissed on mental health grounds in December when a magistrate found he did not start the violence.
The sentence comes weeks after the 25-year-old forward suffered a grand final loss with the Storm.
The former Samoa representative has played 81 NRL games and scored five tries.
His trip to this year's decider proved a rocky road after he suffered a fractured larynx on the eve of the finals.
Blore avoided being put into an induced coma or needing surgery but was told by doctors he would be sidelined for the remainder of the year.
The devastating news followed his previous recovery from back-to-back ACL injuries and a broken wrist when he was at Wests Tigers.
The former Penrith junior star's voice remains raspy and he's set to undergo speech therapy, but he has been given no guarantees of a full recovery.
In a statement on Friday, Melbourne Storm confirmed the club notified the NRL Integrity Unit at the time of the incident and that Blore co-operated with NSW Police throughout their investigation.
"Blore and Storm are grateful for the way the court dealt with this matter and accept the sentence," the statement said.
"Blore is genuinely remorseful for his involvement in this incident."
