Warriors star and former Sea Eagles five-eighth Kieran Foran is the latest player implicated in the NRL's investigation into Manly's salary cap issues.
Australia's Channel Nine reported the NRL are set to examine an alleged commitment Manly had with Foran to facilitate a $150,000 sponsorship deal for the Kiwis playmaker.
Under NRL rules, third party deals allow players to be paid outside the salary cap by non-club sponsors but payment cannot be guaranteed by clubs.
Foran was pursuing the money at the time he was suffering a mental breakdown last year and Nine reported he has made more recent attempts to claim payment from the Sea Eagles.
Manly deny any agreement was made.
