In the latest doping scandal to hit the sport of cycling since Lance Armstrong's confession earlier this month, Danish rider Michael Rasmussen admitted on Thursday that he took performance-enhancing drugs for more than a decade. Rasmussen said he took everything from testosterone and growth hormones to blood transfusions from 1998-2010 in an effort to boost his performance. The 38-year-old Dane said he would quit the sport immediately and cooperate with anti-doping agencies.
