Armstrong breaks collarbone in race crash

American cyclist Lance Armstrong suffered a shattering blow in his comeback bid on Monday when he broke his right collarbone after falling on the first stage of a five-day race in northern Spain.Emerging from a hospital with his arm in a sling, Armstrong said he will return to the United States, where doctors will determined whether he needs surgery. "I'm miserable," said the record seven-time Tour de France champion. "I just need to relax a couple of days and then make a plan." Armstrong could be out for three to four weeks said Jacinto Vidarte, spokesman for the Vuelta Ciclista Castilla y Leon race, following a crash that involved a group of 15 to 20 riders some 20 kilometers from the finish. The injury looks certain to end Armstrong's hopes of challenging for the Giro d'Italia from May 9-31 and must cast big doubts on his plans to chase an eighth Tour crown from July 4-26 in France. The 37-year-old Armstrong was taken to a hospital by ambulance and was seen pointing to his collarbone, CNN's Al Goodman reported from northern Spain.
