Warrington Wolves are facing double disciplinary trouble after incidents involving players and fans.
The club has been given a formal warning by the Rugby Football League about the behaviour of their fans during the Cheshire derby at Widnes over Easter.
Play was stopped and the referee took both teams off the pitch after a smoke canister was thrown onto the field of play in the early stages of the match at the Select Security Stadium on April 2.
An RFL investigation discovered that Wolves fans also threw coins and bottles onto the playing surface.
Warrington were found to be in breach of RFL operational rules regarding improper conduct and misconduct of spectators.
An RFL statement said: "The club were reminded of their responsibility to make best efforts to ensure there are no further incidents at future matches."
Meanwhile the club's forward Anthony England could be banned for up to eight matches after being charged with spitting at an opponent.
The 28-year-old was one of four players sin-binned during a spiteful Super League match between the Wolves and Huddersfield at the John Smith's Stadium on Sunday.
He was shown a yellow card along with Giants captain Danny Brough following an out-break of fighting and apparently had to be restrained as the players continued their argument on the sidelines.
England has been charged by the Rugby Football League's match review panel with a grade E offence which is rated alongside gouging and biting as one of the most heinous crimes that can be committed on a rugby field and carries a suspension of between four and eight matches.
The player does not have the option of submitting an early-guilty plea and will appear before an independent disciplinary tribunal on Tuesday evening.

Warrington Wolves have named Joel Monaghan as captain for the 2015 season and Chris Hill as vice captain.
The pair will take over the role from former captains Michael Monaghan - retired - and Ben Westwood.
Winger Monaghan is embarking on his fifth season with Warrington with 118 appearances and 128 tries to his name to date.
England International Hill joined from Championship side Leigh Centurions ahead of the 2012 season and has gone on to make 98 appearances cementing his place in the side and within the Super League competition.
Head of coaching and rugby Tony Smith said: "Joel's leadership qualities and knowledge of the game made him the stand-out candidate. Over the years he's developed as a leader and has become very influential within the group. He's highly respected by all the players and staff. I'm now looking forward to seeing him develop his leadership skills further and the positive impact it will have on the team.
"Chris' development over recent years is quite remarkable and this again is testimony to the hard work he's put in on and off the field. Chris leads by example and he's not only a future Warrington captain, but I believe a future England captain. Like Joel, Chris is immensely respected by his fellow players."
Smith adds on last year's joint captain Ben Westwood: "Ben still remains an influential and integral part of the team's leadership, as do a number of other players who have missed out on the captaincy. Relieving Ben of this role will allow him to focus on getting back to his best form we all know he's capable of."

Warrington are warming up nicely for a tilt at reigning Super League champions Wigan.
The Wolves, Grand Final runners-up for the last two years, remain on course for a third successive trip to Old Trafford after gaining a hard-fought 30-14 win at Castleford in the first preliminary semi-final.
The line-up for the last four will be completed on Friday night when Huddersfield host Catalan Dragons, after which table-toppers St Helens will select their semi-final opponents under the controversial ClubCall system so despised by Warrington boss Tony Smith.
Saints look certain to avoid Warrington, who finished fifth this year but have beaten their derby rivals on all their previous trips to Langtree Park, and instead pick the winners of the second preliminary semi-final at the John Smith's Stadium.
Smith, who was fined for snubbing ClubCall last year when his club opted to play Huddersfield in the last four, is relieved not to be placed in the same position this time.
"Everybody knows I love ClubCall," he said, tongue in cheek.
"Whether we're picked or whether we're pushed, we don't really care. Obviously we're just happy to be through to the next round, understanding that both teams that are options for us are going to be tough.
"We've had to do it from sudden-death in week one but after week one it's the same for everybody.
"We've had a pretty good five or six weeks. We've been building it up. Our intensity has increased as the season has gone on and hopefully we can keep building it. Who knows how far it can take us?"
Warrington, who lost to Wigan in last year's Grand Final, were in control of their clash with the Tigers from the moment centre Ryan Atkins followed up a charge-down to open the scoring with a fourth-minute try.
Winger Joel Monaghan scored twice, taking his try tally for the season to a remarkable 37, and impressive full-back Stefan Ratchford created second-half scores for Gareth O'Brien and Rhys Evans as the Wolves cruised to victory over a tired-looking Castleford.
