South Sydney are to lodge Greg Inglis' contract with the NRL within the next 24 hours, amid suggestions his switch to the NRL club is in jeopardy.

A club statement on Thursday denied a report claiming NRL salary cap auditor Ian Schubert was set to knock back the terms of the Rabbitohs' deal for the superstar centre.

Having walked away from his deal to join Brisbane, Inglis remains contracted to Melbourne while Souths attempt to finalise a contract for him.

The 23-year-old has agreed to a three-year $1.8m deal heavily backended and involving third party agreements which Souths expect will allow him to fit under the salary cap.

NRL chief executive David Gallop said the league had yet to reach any firm conclusions about the Inglis deal.

"We don't have a contract for Greg Inglis - we've seen a short-form agreement, we haven't seen any of his third party deals and at this stage we're not in a position to even consider registering it," Gallop told Sky Sports Radio.

"Everyone's known for some time that this is a difficult situation brought about by the salary cap breaches at Melbourne and that we need to have the salary cap auditor's approval for any deal that he got at a new club.

"We're not at that point - I feel sorry for Greg, it must be frustrating for him, but we're not at that point yet.

"We don't have all the details of Greg Inglis' arrangements so we're not in a position to register it."

South Sydney maintained registering the deal was a work in progress.

"A short form contract was lodged with the NRL on Monday 15 November," the statement said.

"Within 20 business days of this contract being lodged, the Rabbitohs are required by the rules to lodge a full NRL playing contract.

"The club will be lodging this contract within the next 24 hours.

"Following the lodgment of the full NRL playing contract, NRL salary cap auditor Ian Schubert will review the contract in accordance with rules.

"In the meantime, the club continues to work constructively with the Melbourne Storm towards gaining a release for Inglis from his existing contract."
