'It's just ruined my life': Mullen opens up on drugs ban

NEWCASTLE Knights star Jarrod Mullen has broken his silence on the drugs suspension that has effectively ended his NRL career.

The former NSW halfback copped a four-year suspension in May for being injected with a banned substance - the steroid Drostanolonein - in a bid to recover from a hamstring injury.

In a tell-all interview to air on Seven News on Thursday night at 6pm, the 30-year-old Novocastrian says a physiotherapist he trusted from outside the Knights was responsible for the bungle that has "ruined his life".

"I trusted the bloke. I'd known him for 10 years - he tossed up an amino acid injection to help with the healing," Mullen said.

"After the injection I tore my hamstring two weeks later so whatever was supposed to go in there didn't work anyway."

However, Mullen says he accepts full responsibility for what happened, refusing to name the physio despite the possibility of having his ban reduced from four to two years for doing so.

"I just want to say I take full responsibility for what happened - I'm not here to blame anyone else," Mullen said.

"If someone is saying to you 'I'm going to inject you with a steroid', as a professional athlete you're going to say 'no - no way in the world'. It stays in your system for six to 12 months and I get tested every second week.

"When I did the interview with ASADA they knew it was an accident because you need to be taking five other different things for it to actually do anything.

"If I was intentionally going out there to improve myself to get bigger, faster, stronger - I'm happy to cop the four years.

"It's just ruined my life."

Bursting on to the NRL scene as a teenager, Mullen was touted as Andrew Johns' successor both at the Knights and for NSW. He made his State of Origin debut as a 20-year-old, but played only one game in the sky blue jersey.

He's played over 200 games for Newcastle and represented Country Origin team four times.
