Lance Armstrong's broken collarbone is worse than thought, but the seven-time Tour de France champion said Tuesday he believed he could still be fit for the Giro d'Italia after surgery on Wednesday.

"It's a very common cycling injury, so you hear of guys who have raced two weeks later, and guys who have raced two months later. In my opinion, I think the Giro is still very doable," Armstrong said in a teleconference from Austin, Texas, where he was to have surgery on Wednesday morning.
