Anyone found guilty of racial abuse should receive a NRL life ban, a fired up Johnathan Thurston says.
"Ban them for life, 100 per cent. We don't need that in society or the game - piss them off," the North Queensland co-captain said on Tuesday.
The proud Indigenous All Stars playmaker could not hide his anger over allegations that Newcastle's Dane Gagai was the subject of racist taunts during the Knights' last-round loss to Cronulla.
The NRL integrity unit is investigating the claims with Newcastle.
Gagai had been in tears after Sunday's 62-0 loss to the Sharks at Hunter Stadium but it was thought to be more due to the death of his grandmother rather than a racial slur. However, former South Sydney player Joe Williams said he heard the Knights' flyer being called a "sooky black c***" by a member of the crowd during Gagai's emotional outpouring, News Corp Australia and Fairfax reported.
