Inglis was racially abused as he left the field in the round two clash with Penrith.

The two spectators have been banned from attending NRL events until it is proven they have rehabilitated themselves by addressing their behaviour in an apology and completing an approved cultural training and education.

"Naturally I am appalled at what happened to Greg, especially given my immense respect for him as an Indigenous leader and his status as one of the best Indigenous players of all time," Australian Rugby League Indigenous Council chair Linda Burney said.

"But the NRL has taken the right approach by allowing the persons responsible to return to rugby league only after they have undergone appropriate Aboriginal and Torres Strait Islander cultural training and have issued an apology to Greg and Indigenous community leaders for their comments.

"The best way to stop a repetition of this type of behaviour is through education. I am also pleased that senior Indigenous leaders from the game will help decide whether the person responsible is ready to return to games.”
