I found this on another site CJ. Someone that was watching from turn one
No, I didn't get any pics of the accident, it happened so fast. He started to brake hard, then the rear got a little loose, the rear started to slide to the left, then re-connected which looked as if the rear wheel rolled over his right foot which vaulted him off the bike. It sent him rolling and sliding deep into the grass in turn one. Once he was thrown off the bike rode right down the straight away into the grass of turn one and must have hit a hump in the grass, shot up five feet in the air and did one frontwards flip in the air, and the second flip in the grass. I saw him hobble a bit to the ambulance but never saw him next to the bike in the pit area again, so I wondered if he was okay.
