NRL integrity unit boss Nick Weeks says the investigation into Parramatta players and player agents has not concluded.
"There's a phase of this investigation to come and that's going to involve looking at some of the material we have and the conduct of player agents," Weeks said.
"Ultimately that will be passed across to the agents accreditation committee if in fact we identify material that we think they want to look at."
When asked if players knowingly were involved in salary cap cheating, Weeks said: "The phase of the investigation that has concluded today with the breach notices and the announcement relates to the club and officials".
"There's a piece of work that we still need to do in regards to agents and we will look at the conduct of some players as well. In an ideal world we would have revealed all that at one time.
"It's a bit difficult to make a broad statement across all the different types of conduct we're looking at. In some cases it would be perfectly reasonable for a player to be under the impression that he has a legitimate third-party arrangement with a company. We might look at that from a different perspective from the salary cap rules."
Former Eels chief executive Denis Fitzgerald believes the police should get involved in the incident, citing the payments of up to $3 million over the cap.
"That was the figure that shocked me because that's undisclosed third-party agreements," he said. "That leads to (questions about) is there fraud involved? I do believe the New South Wales police force must get involved and I do believe that the Australian Taxation (Office) should get involved too when that sort of money is being spoken about."
