Cronulla stars Andrew and David Fifita have been stood down by their club, after an ugly incident at a junior rugby league game at the weekend.  The pair will be unavailable for Sharks selection until an investigation into their alleged misconduct is completed.  The club said they were reviewing statements from a host of witnesses, some of which appeared to be conflicting.  "There is a process which must now be allowed to occur to give the players the opportunity to review that information and respond and that process is underway," the Sharks said in a statement.  "As a part of that process the players have advised they intend to defend the more serious charges levelled against them."  The twins could reportedly face a ban of around 10 weeks if they are found guilty.  Andrew and David Fifita.

One match official involved has walked away from his duties and two others involved are set to do the same.  Andrew Fifita was said to be upset after the referee didn't stop play for an injured player.  Earlier, the pair were banned from attending Penrith junior rugby league games for 12 months.  The decision to suspend the brothers was handed down by a Panthers disciplinary committee this morning.  The pair still have the option to appeal the bans but could face further penalties from the Sharks and the NRL.  Were you at the game?

"It should be a long time out of the game," Harrigan said.  "Because that's what they are saying about anyone out there approaching referees, and trying to retain young referees over the abuse they all cop.  "To cop it from a first grader to say I'll smash you or something similar if that is what he has said. To me it has to be rubbed out to set an example, rubbed out for 12 months.  Harrigan said retaining young referees continued to be a problem for the NRL, because of the poor treatment they receive.  "Out there at park football where these young referees don't have any security like first graders do they walk to their cars, or their mums and dads are picking them up they shouldn't be fearing, they shouldn't be worrying about people coming up to them and abusing them," he said.  "Every time you see someone coming up to you you start to feel intimidated or panic about it, you start to think is this bloke going to have a go at me.  "If two footballers walked up to you, first grade footballers that are well known and they say something which was something in a derogatory way, well then there has to be a heavy punishment because they are setting an example to the mums and dads out there."
