Weller Hauraki, Justin Carney and Danny Tickle have been banned for their parts in the Hull-Castleford brawl on Friday.
Hull's Tickle and Castleford pair Hauraki and Carney all pleaded guilty to charges of punching during the home side's 52-0 Super League win at the KC Stadium.
Tickle and Hauraki will serve one-match suspensions while Carney has been handed a two-game ban.
There was better news for Hull over Mark O'Meley, though, with the experienced prop found not guilty of punching at a Rugby Football League disciplinary hearing on Tuesday.
The Australian was sin-binned by referee Steve Ganson for his part in the fracas and was initially charged by the RFL's match-review panel with a grade B offence.
Meanwhile, Widnes will have to do without Gareth Hock for their trip to face Catalan Dragons after the forward was hit with a one-match suspension.
The on-loan England international was found guilty of a Grade B offence of using foul and abusive language to a match official during their 22-22 draw with Bradford.
Hock was dismissed for the offence and his ban means he will now not play in France. He also can't play the following week for the Vikings as they face Wigan, the club he left to move to the Halton Stadium on a season-long deal.
