A string of Storm and Sea-Eagles players could be banned for the rest of the NRL season, including the finals.
Both benches were cleared in an all-in brawl in the Sea-Eagles' win at Brookvale Oval.
Manly forward Glenn Stewart and Storm back-rower Adam Blair instigated the brawl.
Sydney Morning Herald league journalist Brad Walter says the NRL judiciary is planning to come down hard on all involved.
He says there are 10 players facing charges and a number of players, including the main two, could've played their last match this season.
