ASADA grilling shakes former Essendon player Mark McVeigh Mark McVeigh has spoken about his ASADA interview. Picture: Colleen Petch Source: News Limited A SHAKEN Mark McVeigh says Essendon was plunged into its supplement scandal by a "huge rogue element." In revelations that pour serious doubt on Essendon's ability to escape sanction, the former Bomber admitted he was disturbed by what drug investigators had told him during a four-hour ASADA grilling this week. "There are things that you hear in this interview that you know nothing about and you've never heard before and they are quite alarming," McVeigh said. When I say alarming, I mean things that people may have done who are no longer at the club that no one knew about. You think about your family, you think about your health and it's quite serious. McVeigh, speaking on SEN radio, admitted he was left "furious" by some revelations, but said he still believed the players had done nothing wrong. "I don't think we did anything untoward ... but there is a huge doubt and there were things going on that James Hird, the doctors at the club and the players had no idea about," he said. I'm not just talking about being injected with an illegal substance; I'm talking about if you had given blood where that was going and if you were given a substance and it's not checked off properly. I've said all the way along that I was told things were ASADA and WADA approved. If I was given a supplement it was seen that was what it was, but there was some suggestion in my interview that it was not what it was. McVeigh was surprised at how much ASADA knew about Essendon's drug program in a grilling he said put him under enormous stress. "I really feel for the people involved in the footy club," he said. The people that were officiating and the people that should have known things were being told one thing and there may have been something else going on instead, so there was a lot of lying going. I understand checks and balances and governance, but when coaches and doctors were asking what was happening, a person or particular people were telling them one thing, but something else was happening. I can really understand how these players are feeling and I feel it is a mighty, mighty effort for them to be playing football at the top level considering what's going on. McVeigh retired from football last year after 232 games for Essendon. He was vice-captain between 2006-2012.
