MINOR premiers the Sydney Roosters are about to be dragged into the NRL's doping investigations, with two players poised to be interviewed by ASADA.

The Daily Telegraph can reveal that the pair are about to receive letters requesting they attend interviews in coming weeks, while there is also a chance the probe could be extended to an ex-Roosters player now contracted to another club.



It's believed the Roosters players' names came up during the investigation of Canberra Raiders star, Sandor Earl, who last month admitted to trafficking and use of banned peptides.

Roosters CEO Brian Canavan last night confirmed officials were aware of "rumours", but said ASADA was yet to contact the club.



"We've had no contact from ASADA," Canavan said. "The club is not aware of any investigation.



"We are aware that some rumours are circulating that a couple of players and ex-players may be interviewed.



"The club is totally compliant with with the integrity unit's practices and procedures.



"The club has the highest standards in its own governance practice and procedures.



"The club is transparent."



The Daily Telegraph understands the Roosters have been implicated thanks to a common party between them and Earl, who started his career at Bondi Junction before moving to Penrith in 2010.



It's believed the common party has been interviewed by authorities.



Earl's camp have denied any suggestion the 23-year-old has given ASADA information about other NRL players.



Instead, he is providing evidence about sports scientist Steve Dank in a bid to obtain a 'substantial assistance' discount and have his ban cut from four years to 12 months.



Already, the exhaustive investigation has included interviews with more than 40 officials and players from Cronulla, Manly, Newcastle, Penrith, North Queensland, Parramatta and Gold Coast.



ASADA has appointed three full time investigators to the NRL's investigation since August and has more wide ranging powers which allows it to use phone records, emails and other communications as evidence to summons players or officials for interviews.



The NRL is expected to hand down findings from its own integrity unit investigation and the ASADA report at the same time in around four weeks. Senior officials and football staff from at least two of the clubs are in the firing line for failing to exercise their duty of care to players when Dank oversaw their supplements program.



These include Sharks coach, Shane Flanagan, former strength and conditioning coach, Trent Elkin (now at Parramatta) and several other staff members who were sacked from the Sharks several months ago.



They have all continually denied they were involved in any peptide injection program at the club. Mr Dank has repeatedly refused to be interviewed by ASADA, the AFL or the NRL and also denies any wrongdoing.



The NRL refused to comment on the new developments yesterday and would not confirm the names of either Roosters player. We understand, however, that trafficking allegations are part of the investigation.



The latest revelations that players from yet another club may be involved in the peptide scandal underlines the seriousness of the allegations made in February this year.



In the AFL, the Essendon investigation findings will also be handed down in coming weeks, with at least three senior football officials, including suspended coach, James Hird, also facing serious charges of breaching their duty of care to players.



While AFL boss, Andrew Demetriou has denied newspaper reports that life bans may be slapped on several Essendon officials, The Daily Telegraph understands ASADA's report outlines their alleged involvement in the administration of peptides to the entire team over a 12 month period.



Both the NRL and the AFL are signatories to the WADA and mercy of the drug agencies if violations are uncovered. The NRL says it will only deal with the facts as they come to light and these will be released in mid-October.
