Could we abstain from wishing crashes on any cyclist? I know Contador is the evil guy of the day, but from disliking him to wishing he would crash, there is a huge distance... I find such wishes appalling.

Horner hit his head hard. If he has a concussion (which it looks like the case, judging by his confusion at the finish line about actually having crashed and finished -- see the video from bicycling.com clip here), I hope he does not start tomorrow. It would be too dangerous if he were to fall again.
