Chief medical officer for the Amgen Tour of California
Stage 1 Post-Race Comments

"70 miles into the race (Dave Zabriskie) had a moderate speed accident
and hit his head. He was a little bit foggy and decided it was best not tocontinue on, and he's out of the race. This is one of the more difficult things about working in a race like this. In this situation if he has an intact neurological exam, you can continue to let him ride. It's almost like a "stress" test when you get back on your bike. The decision was fairlystraightforward when he got back on his bike. He had a mild concussion."

We all wish Dave a quick recovery and that he's able to be back on his bike soon!
