Kerevi was in the crowd watching the angry fan hurl abuse and was part of the group of people who pulled his Reds teammate and the man apart.
The injured Wallabies star took to Instagram on Sunday to share his side of the story.
"Lukhan came in to help out because that guy was swearing around his family," Kerevi wrote.
"That altercation only happened because the drunk fan told Lukhan to 'play with some heart'.
"The fact that he was even on the field speaks volumes.
"So for everyone throwing chat at my boy... Shut your mouth!
