Yamaha's Jamie Hacking—fastest in this morning's 600 Supersport session—crashed in Superstock practice this morning and injured his neck.

Yamaha Team Manager Tom Halverson said moments ago that Hacking tried to ride off after over-cooking the chicane and then crashed and hit the wall of bales placed there this year, face-planting the bales and injuring his neck. He hasn't left the track to get x-rays as yet and is currently working with a team therapist to sooth his battered body.
