Up to 10 player managers, representing most of rugby league's elite players, face possible criminal prosecution and NRL de-registration, following a joint NSW Police/Integrity Unit investigation into the Parramatta salary cap breaches.

Four prominent player managers – Wayne Beavis, Sam Ayoub, George Mimis and Paul Sutton – have already been served with police warrants during a State Crime Command's Strike Force Rhodium operation on Thursday, when their premises were raided and information taken away.

It has been speculated six agents were on the NRL hit list but Fairfax Media understands RL Central is scrutinising the role of up to 10 player managers, representing a significant proportion of the game's players and, potentially, athletes from other sports.

NSW Police recently announced two very significant and high-profile investigations into rugby league – player managers and match fixing – with a third, serious fiduciary breaches by Parramatta officials, continuing. The resources police dedicated to Thursday's raid on the offices and premises of the four player managers indicate the seriousness they attach to the three enquiries.
