Canterbury-Bankstown are set to drag Josh Addo-Carr in for a Head Injury Assessment after the winger revealed he was "knocked out, put to sleep" at the Koori Knockout over a fortnight ago.

Addo-Carr was involved in an all-in brawl at the annual Aboriginal rugby league tournament while playing for Sydney All Blacks against eventual champions Walgett over the October long weekend.

Recounts and allegations of the incident, which spilled out to involve crowd members, varied.

An organiser told National Indigenous Times the scenes had been blown out of proportion in the media, and that Addo-Carr was left relatively unharmed by a dangerous tackle early-on in what was a highly-physical contest.

Speaking on his podcast Let's Trot, co-hosted by former Penrith and Rabbitohs wing Josh Mansour, Addo-Carr admitted he was knocked out at the start of the game, but played on.

"I ended up getting knocked out, put to sleep five-10 minutes into the game. You know, it was a fiery game," Addo-Carr said.

"It was unfortunate that that incident (the brawl) happened at the end of the game. But that's the Koori Knockout."

NSW and Kangaroos representative was handed a two-game suspension and kicked out of the national side's squad ahead of their Pacific Championships opener against Samoa on Saturday.

The NRL confirmed his sanction would be served throughout the Kangaroos' first two games.

Addo-Carr said he will appeal the ban, and he had initially thought "nothing was going to come of it" with the media spinning the story to look like he was entirely at fault.

"This is the first time ever..I've never been suspended. I'm a cleanskin," he said.

According to NewsCorp, the Bulldogs and NRL are concerned by his continued involvement in the game after being concussed.

Canterbury are planning to bring Addo-Carr in to undertake HIA protocols for delayed symptoms this week.

The NRL is understood to have contacted all clubs to remind them the Koori Knockout is not a fully authorised tournament.

Addo-Carr said his disappointment was heightened by his passion for the Knockout.

"It's something we grew up going to, being a part of..it's in our blood," he said.

"It's just about representing your mob, representing your people...and your community. For myself, I love being a part of it every year. The way it panned out this year, it was pretty disappointing.

"There's no better feeling than winning a Koori Knockout. It's just that time of the year that all blackfellas love being a part of."

Addo-Carr said for Indigenous players, representing your mob sits on the same level as playing for Australia.
