This is a huge bummer for Shonny, the newly signed Luna Chix racer. 
From Cyclingnews.com on Stage 2:
A mid-race crash at the back of the pack seemed to bear this out. Shonny Vanlandingham (Luna Women MTB) was jostled from behind while the women negotiated speed bumps, potholes and each other. She hit the pavement hard and slid headfirst into a cement gutter, smashing her helmet and breaking her collarbone.
"She was conscious and she could talk to us to tell us where it hurts," said Luna Women MTB DS Waldek Stepniowski. "She's kind of beat up. Lots of road rash. The helmet was in really bad shape, so I think she had a major concussion."
