Featherstone Rovers CEO Davide Longo has threatened supporters with playing a game behind closed doors or banning alcohol from games.
This news comes after another incident involving fan behaviour at the club, after a fan allegedly abused a match official during their 26-24 defeat against Toulouse on Saturday.
The club was issued with a £100,000 fine earlier in August after several incidents involving fan behaviour earlier this year.
Longo told BBC Radio Leeds: “We’re zero tolerance for this now.
“It brings the club into disrepute. We’re trying to protect the family image of the sport.
“We’re not saying that Featherstone is squeaky clean and other clubs have their issues, but we’re not going to tolerate it.
“We’ve banned three of the fans and I’ve threatened the supporters that if it was to continue we’d look at playing games behind closed doors or banning alcohol.
“If that’s what it takes to get rid of the people who are letting us down then we’re going to do it.”
