Johan Bruyneel, disgraced cyclist Lance Armstrong's former manager during his drug-tainted seven Tour de France wins, has left his current team RadioShack on Friday, the outfit announced. "From this day on, Johan Bruyneel will no longer act in the position of general manager of cycling team RadioShack Nissan Trek," a statement said on the team's website. The decision comes just two days after the United States Anti-Doping Agency (USADA) condemned Armstrong for being at the heart of the biggest doping conspiracy in sports history.
