He says he did not receive any anti-doping training or education.
A Carlow footballer has accepted a 4 year ban for testing positive for a banned substance.
Ray Walker returned to the county senior football panel last November and tested positive in February for a performance-enhancing drug meldonium.
The 35-year-old says he did not intentionally take any banned substance and added that the acceptance of his ban is not an admission of intentional wrongdoing on his part.
Walker also says he did not receive any anti-doping training or education.
Carlow GAA have said in a statement that they won't be making any comment until the disciplinary process is complete.
