SANDOR Earl is set to break his silence about becoming the ASADA investigation's first scalp in a paid television interview next week.

The Daily Telegraph can confirm Earl’s management has been in negotiations with several networks since the 23-year-old admitted to trafficking and use of banned peptides on August 28.

It’s understood Channel Nine has won the bidding war for Earl’s story, which will be one of the most anticipated sports interviews of the year.

Channel Seven’s tell-all with former Essendon high performance manager Dean Robinson, who unloaded on suspended head coach James Hird, drew huge ratings across Australia.

Coincidentally, Robinson was in the Roosters dressing rooms and player dugout to support his brother, Trent, in last Saturday night’s qualifying final against Manly.

It’s believed Seven paid Robinson more than $100,000 for the 45-minute interview. Sources close to Earl last night said the deal with Channel Nine was yet to be finalised.

However, the plan is for a prerecorded interview to be aired on next Thursday night’s Footy Show.

The former Raiders and Panthers winger last week returned to Sydney from a brief overseas trip to Asia, which he took on the day after the NRL made his admission public.

Earl’s charges carry a maximum four-year ban, but he’s co-operating with ASADA in a bid to obtain a substantial assistance discount that would cut his suspension to 12 months.

Although Earl has admitted to trafficking peptide CJC-1295, the circumstances around his offence do not relate to the direct sale or supply of banned substances.

Under the WADA code, trafficking can also include "transporting" or "delivering" banned substances.

Of concern for Earl was a fateful drive he made from Mascot to Cabramatta toward the end of 2011, when he was recovering from a double shoulder reconstruction while contracted to the Panthers.

At the same time sports scientist Stephen Dank was consulting with the club and advised Earl about the peptide-based remedy. Dank referred Earl to Dr Ijaz Khan, who worked at the Cabramatta clinic known as Injury Care Pty Ltd, where he had multiple rounds of injections.

Earl told ASADA that on one occasion he collected a substance from Dank in Mascot and drove it to Cabramatta for his appointment with Dr Khan, which, under the WADA code, constitutes trafficking.

Dank has repeatedly denied any wrongdoing or giving athletes banned substances.

ASADA used text messages intercepted from Dank’s phone to build their case against Earl, who is considering his own legal action over claims he was told the substances were not prohibited.

Earl will attest his knowledge of Dank’s practices in bid to gain ‘substantial assistance’, but no other NRL players or athletes have been implicated in his case.

He met with ASADA again this week, but might have to wait until next month before learning the length of his ban.
