The Philly Daily News says Lance Armstrong suffered a broken clavicle (collarbone) in a pile-up at a race in Spain yesterday.
Armstrong will need surgery, leading to questions about whether he'll be able to contend for an eighth title in July.
"I'm alive!" he wrote on his Twitter feed. "Broken [right] clavicle. Hurts like hell for now. Surgery in a couple of days. Thanks for all the well wishes."
Armstrong will fly back to the United States to have surgery.
Astana team leader Johan Bruyneel said on his Twitter feed there were no complications in the break, and suggested Armstrong could be riding soon.
In London, The Times thinks Armstrong's exit might be good for pro cycling:
Until last weekend, when the real business of Armstrong as an elite cyclist and Tour contender began, everything had gone to plan. There had been much glad-handing around the world, some showboating in a couple of lesser races in Australia and California, the now-traditional casual put-downs of anti-doping campaigners and a little sledging towards his major rival — on this occasion, his own Astana team-mate, Alberto Contador...
...For his detractors — and there are many both in Europe and in America — the prospect of the multi-millionaire packing up his train set and heading back to Texas will be a huge relief. While publicity accompanies his every move, and a key part of the raison d’etre for his comeback is his global cancer campaign, suspicion also shadows him at every turn of the pedals.
The platform of transparency and openness with which he trumpeted his return has quietly been forgotten, while Don Caitlin’s unimpeachable testing programme — that Armstrong insisted would go ahead — was poorly thought through and never got off the ground. Arm in a sling as he flies home to Texas, he will now be desperate to prevent his racing comeback following the same fate.
