The Manly Sea Eagles announced they will co-operate with the NRL and New South Wales Organised Crime Squad in light of claims of alleged match-fixing last season.
NSW Police confirmed on Thursday they were "in the early stages of examining information to alleged match-fixing in the NRL" as the turbulent season continued for the Australian rugby league.
The NRL has already had to deal with salary cap breaches by the Parramatta Eels and it confirmed it was co-operating with police on the matter.
Reports cited two Sea Eagles matches and the club moved to assure supporters of their co-operation with any investigation.
"The owners, board and staff of the Manly Warringah Sea Eagles want to assure its members, corporate partners and supporters that the club will fully co-operate with the NRL and NSW Organised Crime Squad in its examination of information in to alleged match-fixing," a statement from the club read.
"The club emphatically states: it values the integrity of rugby league above all else and will ensure full co-operation is provided to any investigation
"It has had no contact from the NSW Police or NSW Organised Crime Squad with respect to the alleged match-fixing in the NRL
"It is bitterly disappointed that the club's hard earned 70 year reputation for fair play has been unfairly tarnished by imputations raised by some media outlets involving two Sea Eagles matches last season, albeit there is presently no formal investigation."
Manly chairman Scott Penn and chief executive Joe Kelly added in a joint statement: "The Sea Eagles fully support the strong stance by NRL CEO Todd Greenberg that any player found guilty of match-fixing be banned for life.
"We will continue to support our players 100 per cent and give them the presumption of innocence - particularly against unfair mainstream and social media innuendo.
"We will continue to monitor the situation and openly communicate with members, corporate partners and supporters if any further information comes to hand.
"Meanwhile, we will concentrate on winning football games starting with Canberra in Canberra tonight."
