Simona stood down over NRL betting scandal
Wests Tigers centre Tim Simona is facing a ban after becoming embroiled in a betting scandal.
The NRL issued Simona with a notice to cancel his registration after he was alleged to have broken rules relating to gambling on the game.
Simona has the right to appeal but has been stood down from training and will not be allowed to play before the matter is finalised.
He was withdrawn from the Tigers squad for their final trial against North Queensland at Campbelltown on Friday night.
The governing body did not reveal the allegations against Simona.
The NRL betting code states "No NRL employee, NRL club employee, player, player manager or game official is allowed to participate, or be directly or indirectly involved in any way, in gambling in relation to rugby league.
"Or be involved directly or indirectly, in the provision of information not already in the public domain that might assist another person to gamble in relation to rugby league."
The Samoan international has played 79 games for the Tigers since making his debut in 2011.
He was recently linked with an immediate move to the Gold Coast as the Tigers face a battle to balance their salary cap this year.
The Tigers are facing a battle to get under the salary cap before the start of the year and Simona's exit could ease their woes.
Despite being just seven weeks into the new year, it's the second scandal to strike the club.
Forward Kyle Lovett last month was stood down after pleading guilty to drug possession having been caught with cocaine on a night out.
The club said on Friday in a statement: "Wests Tigers have been made aware that player Tim Simona is currently under investigation by the NRL integrity unit in regards to allegations of breaches of the rules relating to gambling on NRL matches.
"The club will be making no further comment until the investigation is complete."
The Samoan international has played 79 games for the Tigers since making his debut in 2011.
In 2014, the NRL banned five players after they were found guilty of betting on games involving their clubs.
Ethan Lowe, Cody Nelson, Hymel Hunt and Slade Griffin were all stood down for two matches for gambling on games involving their clubs but which they did not play.
Manly premiership-winning winger David Williams was rubbed out for the rest of the year for gambling on several games including those in which he played.
While none was implicated in match-fixing or spot-fixing, the NRL promised a zero-tolerance policy.
The NSW police organised crime squad last year began probing match-fixing allegations and investigating several matches involving Manly.
In 2011, Canterbury forward Ryan Tandy was fined $4000 and put on a good behaviour bond for his role in a spot-fixing plot.
He was found guilty of purposely giving away a penalty in the hope of conceding a goal however the sting failed to come off after North Queensland took a quick tap and scored a try.
Controversial former South Sydney player John Elias admitted in his biography that he had attempted to fix a game against Western Suburbs but the deal fell through.
