Adelaide 36ers remove Facebook joke about Essendon drug saga and Lance Armstrong THE Adelaide 36ers have had to rectify an embarrassing gaffe - a dig at the Essendon Football Club and disgraced cyclist Lance Armstrong - on social media this morning. Earlier today The Sixers' official Facebook page posted a picture of Armstrong wearing a Bombers jumper to promote its footy tipping competition. The Facebook page updated the hot race for its footy tipping title by highlighting the Friday night blockbuster between top-ranked Hawthorn and second-ranked Essendon with the digitally produced image of Armstrong as a Bomber. The Advertiser.com.au asked the Sixers about the image and within minutes it was dragged down and rebuilt without Armstrong's doctored image, keeping the Hawks and Bombers logos. In January this year Armstrong admitted in an exclusive interview with talk show queen Oprah Winfrey that he used banned substances to help him win his record seven Tour de France titles (1999-2005). The Bombers are currently embroiled in an ASADA drugs investigation after claims players were prescribed injections of allegedly banned substances.
