A U.S. federal judge has dismissed seven-time Tour de France winner Lance Armstrong's effort to block a probe into whether the retired cycling champ cheated by using performance-enhancing drugs.
Last month, a U.S. District Judge dismissed Armstrong's original bid to stop the U.S. Anti-Doping Agency from proceeding with its case, but allowed Armstrong's lawyers to file an amended lawsuit.
However the revised complaint has now been thrown out, though it was dismissed without prejudice, meaning Armstrong can try again.
Accusations of doping have dogged Armstrong, who won seven straight Tour de France championships between 1999 and 2005 when he ascended to the top of the cycling world after overcoming cancer.
