The sanction against O'Sullivan, one of the best talent spotters in the game, relates at least in part to his association with notorious punter and brothel owner Eddie Hayson.

Hayson, who deposited more than $700,000 in O'Sullivan's TAB account over a number of years, denied he ever gained any financial benefit from their friendship.

O'Sullivan has been sidelined since mid-August, with the NRL opting to suspend him after he responded to an intention to cancel his registration. It's understood O'Sullivan is considering whether to appeal the decision.

Asked last month, during a press conference arranged by celebrity spruiker Max Markson, whether O'Sullivan had ever provided him with inside information, Hayson said: "Um, I don't believe so. I've known Peter for a long time so I want to be very accurate in what I say. No, I don't believe he has."

O'Sullivan was at the Melbourne Storm during the salary cap scandal but escaped sanction. Former NRL chief executive David Gallop said only legal advice prevented the governing body from recommending O'Sullivan be sacked from his subsequent job with the Roosters.

The NRL's former salary cap auditor Ian Schubert uncovered evidence that O'Sullivan failed to disclose third-party payments in player contracts. He was also found to have "deliberately concealed" the real amount paid to at least two players.

O'Sullivan is considered one of the best game's best judges of talent, having unearthed a slew of superstars including Greg Inglis and Israel Folau. More recently, he has been credited with bringing exciting fullback Latrell Mitchell to the Roosters.

The Organised Crime squad is continuing to examine betting patterns on at least three NRL games to determine whether any criminal offences have been committed. The Manly Sea Eagles are the common denominator in all three matches.
