Kieran Foran will reportedly have to front the NRL's integrity unit before he can make a return to the sport with the Warriors.
Reports suggest Foran is close to signing a one-year deal with the New Zealand based club, after leaving Parramatta earlier this year to deal with personal issues.
However any potential return to the game will have to be cleared by the league's integrity unit, who it's suggested want to talk to him about his close relationship with controversial punter Eddie Hayson.
"Kieran is not a registered player with the NRL, so the NRL would have to be convinced that he is fit and proper to be a registered player," an NRL spokesman told News Corp Australia.
The NRL would also check his mental state and ensure he is not implicated in NSW Police's match-fixing investigation before approving his contract.
Warriors boss Jim Doyle has also denied reports the club is close to signing Foran.
