The Sydney Roosters have stood down club official Peter O'Sullivan, while the NRL are seeking his deregistration over alleged links to reported match-fixing orchestrator Eddie Hayson.
O'Sullivan is the first person to be stood down as the NRL investigates claims of fixing that have emerged in Australian media.
A match this season between the Manly Sea Eagles and Parramatta Eels is under investigation by New South Wales Police, while two fixtures from the 2015 campaign are also reportedly subject to scrutiny.
AN NRL statement read: "The NRL said today that Sydney Roosters official, Peter O'Sullivan has been issued with a Notice of Intention to Cancel his Registration.
"The spokesman said the proposal to cancel his registration related to alleged breaches of the NRL Rules.
"Mr O'Sullivan has been given the opportunity to respond to the Notice and the NRL will make no further comment at this time."
The Roosters added: "Sydney Roosters CEO, Mr John Lee, confirmed that a club employee is suspended. This is following the receipt of a notice from the NRL.
"Mr Lee indicated that the employee will be afforded procedural fairness while this matter is being dealt with. He also stated that the matter is subject to an appeal process."
