Four Holden Cup under-20s rugby league players face a total of up to 14 weeks' suspension following Saturday night's ugly all-in brawl at Campbelltown Stadium.
As promised, the NRL on Monday came down hard on the brawlers after two players were sent off and another two were sin-binned during the Wests Tigers-Canberra game.
NRL boss David Smith issued all clubs a warning in the wake of Paul Gallen's State of Origin I scuffle with Nate Myles that fighting would not be tolerated - and the league has followed through.
Under the game's new no-biff policy, players will automatically be sin-binned for throwing a punch and the crackdown includes the Holden Cup.
The match review committee has hit Canberra's Tahakilu Pangai the hardest, slapping him with a grade-five contrary conduct charge.
Pangai can accept a three-game ban with an early guilty plea or fight the charge and risk copping a five-match suspension.
Teammate Mitchell Barnett was sent off and charged with grade-four contrary conduct and can take a three-match spell with an early guilty plea or be sidelined for four games if he unsuccessfully challenges the judiciary.
The Tigers' Nathan Brown was also sent off but initially refused to leave the field.
He copped a grade-three contrary conduct charge and faces two weeks out or a three-game ban if found guilty at the judiciary.
Fellow Tiger Kyle Lovett also faces two or three games in the stands after being hit with grade-two contrary conduct.
