James Tedesco will be investigated by the NRL's integrity unit after a woman claimed he made a racial slur against her in Sydney last week.

The NRL formally received a complaint from a woman on Sunday afternoon, after a social media post late last week.

In it, the woman's sister claimed the former Dally M medallist said "Squid Game" at the 20-year-old of Vietnamese descent when he walked past her in Bondi on Thursday.

Tedesco is expected to deny the claims and has told the Sydney Roosters he was simply talking about Netflix's popular South Korean series when the woman overheard him.

The NRL has reportedly made contact with a woman over an alleged incident.

"Last night you felt compelled to say "squid game" at my sister when you walked past her outside of Beach Road in Bondi," Katherine Trinh wrote on Instagram last week, tagging Tedesco in the post.

"My dad used to tell stories of the racism he faced when he first moved here 30 years ago, my sisters and I can all recount racism we suffered throughout school.

"And now one of them can remember when an entitled footy player was racist to her just last night."

Ms Trinh claimed in the post that the NSW State of Origin captain had been called out on the comment when it occurred, to which Tedesco responded, "Do you know who I am?"

It adds to a long list of matters for the NRL's integrity unit to consider in their off-season.

Sam Burgess' situation is one of those, with the NRL able to ramp up their investigation into claims last year that alleged drug use and domestic violence behaviour had been covered up by South Sydney.

The Rabbitohs strongly denied the claims by Burgess' ex-partner Phoebe, while the NRL can now speak to witnesses after a police investigation into Burgess was last week dropped.

An outcome is expected in the next few weeks on that matter, as well as a possible suspension for Burgess' brother George after he pleaded guilty to a road rage incident.

George Burgess's charge came just weeks after joining St George Illawarra.
