The NRL is investigating Tim Simona’s dealing with a charity and whether he failed to forward it money raised from auction items.
The 26-year-old is already facing a possible life ban over alleged gambling offences and has been stood down indefinitely.
The Wests Tigers centre this week faced the NRL integrity unit to respond to the charges after being handed a notice to cancel his registration.
During his interview he was also questioned about his dealings with a charity.
An NRL spokesman said he was questioned about several social media posts relating to jerseys he was putting up for auction for the charity.
He is facing scrutiny over whether the money was delivered to the charity.
The NRL integrity unit has’t handed down its verdict and Simona is facing the prospect of being rubbed out of the game indefinitely.
He has reportedly been accused of placing small bets on opposition players.
NRL chief executive Todd Greenberg has maintained the game must take a strong stance on betting violations and match fixing.
