Bulldogs superstar Josh Addo-Carr has been knocked out during a Koori knockout fixture.

The NRL icon was on the receiving end of a brutal high tackle before an all-in brawl erupted between the Sydney All Blacks and Walgett.

The severity of the brawl was evident as the police had to get involved in the fracas.

Addo-Carr's opponents in Walgett included NRL talent such as Jack Wighton and boxing promoter Matt Rose.

The Fox took his frustrations to social media following the incident saying, โ€œTell who really got knocked out in the brawl, play dirty cop it.โ€

A concern for Kangaroos fans is whether this injury could impact the 28-year-old's selection for the Kangaroos squad for this year's Pacific Test series.
