The NRL says it is not yet in a position to notify what are believed to be six clubs that have been under investigation as part of the explosive probe into Australian sport.
The AFL yesterday announced multiple players from Essendon and one player from another AFL club were being investigated for the use of performance-enhancing drugs.
It came after federal Justice Minister Jason Clare said clubs from both codes involved in the Australian Crime Commission report could now out themselves.
But the NRL said it was yet to inform the clubs involved in the probe into the use of banned substances and links with organised crime within the code, and hoped to do so within the next two days.
However, even once they have been told, it will be up to the clubs to decide whether to go public.
