The NRL has this morning reaffirmed its stance that racism will not be tolerated at any level of the game.

It follows a racist comment that was posted on Brisbane player Ben Barba's Instagram account by a player registered in a CRL competition.

"This is a serious matter. Racism will not be tolerated in any form," NRL Chief Operating Officer, Mr Jim Doyle, said.

"Rugby league is an inclusive game and there is no excuse for behaviour that vilifies any member of the game or the community.

"We are in the process of speaking with the individual involved and his family."

ARL Indigenous Council Chair, Linda Burney, added: "We are treating this very seriously and are working with the NRL and CRL to ensure this young man understands the implications and ramifications of his actions."
