Broncos half Ezra Mam has reportedly rejected an offer to meet in person and accept an apology from Spencer Leniu after the Roosters forward admitted to calling him a "monkey" in Las Vegas last weekend.
According to the Courier Mail, Leniu was prepared to pay his own way to Brisbane after contacting the rival club to organise a meeting before Mam turned him down.
It's understood Mam's mother was also notified by Brisbane of the offer.
Leniu admitted to saying the racial slur on Thursday.
According to Fairfax, Mam and Broncos teammates Payne Haas and Billy Walters have provided written statements concerning the incident to the NRL's judiciary panel as evidence.
The fallout has extended beyond the Broncos and Rooster, with a number of current and former Indigenous players expressing their support for Mam.
An online tussle has appeared to have broken out between Rabbitohs fullback Latrell Mitchell and former St George player and world boxing champion Anthony Mundine on the issue.
In a social media video posted on Thursday, Mundine claimed the Mam-Leniu incident didn't amount to racism.
"It aint racism. When two brothers are brown…you can slur each other…because that's what they are," Mundine said.
"I think they oughta toughen up in that sense. It's not racism. If it's a whitefella saying it to a Blackfella that's a different story."
In a direct response via social media, Mitchell said: "This what our people get told to do and continue to be told; 'Be quiet fall in line'."
Mitchell labelled Mundine's argument "absolute bullshit".
"I don't agree with this and if you do, do better," he wrote.
"Don't dilute the oldest living culture on earth".
Late on Friday evening, Mundine offered his own response to Mitchell saying he was "just stating facts".
"When it came to exposing racism & bigotry in sport, I was the pioneer. I paved the way. In fact, I was giving a voice & standing up for Aboriginal people's rights when you were still in nappies," Mundine wrote.
Mundine went on to say Mitchell has been "underperforming for far too long" and "despite what you might think, you're no Greg Inglis & you're certainly no Anthony Mundine".
"Despite your disrespect, I want you to succeed and excel. Your success fills me with pride & honour, but you need to learn to respect those who paved the way for you."
