The National Rugby League has rejected an application by the Sydney Roosters to register Blake Ferguson to play in the competition this year.
Chief operating officer Jim Doyle says the decision was based on an assessment of Ferguson's record of conduct over the last two years.
In addition, he says Ferguson had given an undertaking that he would undergo a program of clinical support and counselling before the NRL would consider registering him and this is not yet complete.
Doyle says the NRL would consider any future application for Ferguson to return to the NRL.
However, he warned that a relevant factor in the decision would be whether he has engaged in and completed an appropriate clinical support and counselling programme.
