Quotes from the news wire:
I'm very hungry, it's been a year and I'm watching the race on TV now. It's really such a great memory. We all know when we're doing things you have higher chance of an injury. That's part of it. But I definitely want to get back out there, but No. 1 is to get back to 100 percent strong or nearly 100 percent strong before I can make that happen.
It does look like something that would have, maybe in a way, (caused the wreck), it wasn't like there were five or six cars around me. There was only one car ahead of me, and he darted to the right, and I darted to the left, which was the standard procedure. But I never saw that car there. So yeah, maybe the sun definitely had some sort of impact.
