The NRL has cleared Parramatta of any breaches of the salary cap following an investigation into a series of real estate investments by Eels players during the 2002-03 season.

The Eels had been under the microscope after it was revealed investments made by Luke Burt, Fuifui Moimoi and former players Dean Widders and John Morris had been guaranteed by recently-appointed chairman Roy Spagnolo and property developer Vince Lombardo.

The probe, led by NRL salary cap auditor Ian Schubert, investigated promises made to the players that they would not lose money from the investments.

Spagnolo, who was not connected to the club in an official capacity at the time, has always denied any wrongdoing and the investigation ruled on Thursday there was no breach of the salary cap.

"While it appears that a number of investments were enthusiastically recommended to players by people connected to the club there is no evidence to suggest the financial transactions provided any benefit that would have amounted to an illegal salary cap payment," said NRL chief executive David Gallop.

A statement released by the NRL said it saw no need to continue investigating the matter unless fresh evidence materialises.

"We will always take into account any further information that comes to light on any matter but see no evidence that would warrant ongoing investigation at present," the statement read.

The NRL said it is also continuing to closely monitor allegations made in court last month about payments made to Brisbane Broncos players by high-profile individuals associated with the club.

Former Broncos chairman Don Nissen suggested in court last month that payments had been made but details of amounts and frequency have not emerged.

"Given that the issues relate to officials no longer at the club and players who have since left the club the NRL, while continuing to look for additional information, has determined that the matter should remain open until all relevant testimonies have been given in court," the statement said.
