A few minutes ago in the first AMA Supercross class practice, San Manuel Yamaha's Chad Reed went down hard in a technical timing section and crawled off to the side of the track. The practice was red flagged and they had to take Reed off the track on an Asterisk Medic Mule. He looked to be favoring his right arm or wrist. Here's hoping he's okay. We'll keep you updated as soon as we learn more.
