Featherstone are to introduce crowd segregation after being fined £10,000 by the RFL following a second incident of misbehaviour.
An investigation was held into unacceptable language by a section of their fans during their Championship match against Bradford, having previously been fined over two incidents at a game against Rochdale.
They will segregate fans for the visit of Leigh on Sunday.
Featherstone chief executive Davide Longo said: “We are extremely disappointed that a small section of people has let the entire club and game down.
“We encourage fans to create an atmosphere but we must respect everyone within the stadium and adhere to the stadium regulations.
“We are incurring fines that were never factored into our budgets and this will now impact on the club moving forward.
“We will continue to monitor the current situation and we will issue banning orders to anybody found to be using foul and abusive language.”
