Canberra cyclist Michael Rogers has broken his silence after testing positive for the banned substance clenbuterol.

Rogers released a statement on his Twitter account on Friday night in relation to his positive test at the Japan Cup on October 20.

''I would like to make it very clear in the strongest terms possible that I have never knowingly or deliberately ingested clenbuterol,'' he said.

''I can advise that during the period 8th-17th October, before arriving in Japan, I was present in China for the World Tour race, Tour of Beijing.

''I understand that it has been acknowledged by the World Anti-Doping Agency, as well as other anti-doping bodies, that food contaminated with clenbuterol is a serious problem in China.

''In the following weeks I will have the opportunity to explain this unfortunate situation to the UCI [International Cycling Union], in which I will give my full attention and co-operation to resolve this issue in the quickest time frame possible.

''I would personally like to thank those around the world who have shown compassion and understanding of this situation that I've been placed in.''

On Thursday, Rogers' family had professed the star's innocence.
