Alberto Contador and Daniele Colli both went down in the big crash at the end of the sixth stage of the Giro d'Italia and both have undergone medical examinations after the stage.

Contador underwent x-ray and CAT scans of the left shoulder that was injured during the crash. Clinical examination revealed a slight instability of the left shoulder joint, as compared to the right one. He experienced slight pain.

"Alberto is now going to the hotel, where the team doctor, Pete Daniels, is going to asses whether there is any damage, and what its nature might be," manager Stefano Feltrin said after the stage. "You all saw the fall: he got caught in a crash at full speed in a bunch sprint and went down pretty hard. We have applied ice to both knees and shoulders. His elbows and knees seem to be OK. There don't seem to be any broken bones, but in that sort of crash, you cannot know what has happened until you have been examined.

"Yes, it is possible that he won't start tomorrow. Until the doctor has seen him, we can't know the consequences. In the morning, when we have reliable information, we'll decide what to do.

"First, our team doctor will evaluate him and then we'll decide. The race organisation has put its medical staff at our disposal. There is a hospital nearby. When we know, we'll decide what happens next.

“I saw a bad film like at last year’s Tour, but I hope with a different ending. He doesn’t have serious pain and that’s already a good thing. He couldn’t put on the jersey on the podium because he was wearing an ice pack."

Colli underwent x-ray examinations that confirmed a compound fracture of the left humerus, while CAT scans ruled out further fractures or damage to the internal organs of the chest and abdomen.
