The six NRL clubs mentioned in the Australian Crime Commission report are to be briefed by the Australian Sports Anti-Doping Authority later on Tuesday.

Australian Rugby League Commission chief executive David Smith told a media conference the briefings would take place but he could not give a timeline on how long the on-going investigations would take or when specific details might be made public.

Manly, Cronulla, Penrith, Canberra, North Queensland and Newcastle are the NRL clubs mentioned in the Australian Crime Commission report into sports doping and corruption.

They were advised by the NRL on Monday night but given no further information, leaving them unaware what they were being investigated over.

“There is a briefing with ASADA and respective clubs as part of an ongoing investigation,” said Smith.

“It will take the ongoing investigations to the next stage. I can’t pre-judge how long that will take.”

Smith said he understood the frustrations of clubs and fans but continued to emphasise that legal process needed to be followed.

The newly-installed CEO said he was confident the game would come out of the ordeal stronger, having set up their independent integrity unit headed by Tony Whitlam QC as a result.
