Lance Armstrong believes French doping officials may ban him from riding in this summer's Tour de France over a report that he violated protocols during a recent drug test. "There's a very high likelihood that they prohibit me from riding in the Tour," a somber Armstrong said Friday in a video statement posted on his Web site. "It's too bad. The tour is something I love dearly." France's anti-doping agency, known as AFLD, has said the American did not fully cooperate with a drug tester when he showed up at Armstrong's home in France to collect blood, urine and hair samples from the cyclist on March 17.
