There wasn't a lot of big-time news in practice, outside of the heavy crash by JGR Yamaha's Cody Cooper who got out of shape in a rhythm section in his second practice session and hit the ground hard. It took him a long time to get up, and when he did, he was severely favoring his lower left leg and appears to be out for the night.
Broc Hepler's replacement at Team Yamaha, Sean Hamblin, looked as strong as can be expected since he's racing on a week's notice and hasn't raced supercross since 2006.
Again, in the second practice sessions, San Manuel Yamaha's James Stewart was the only rider to dip into the 52s with a 52.557 fastest time and a 52.630 second-fastest time. Next up was Rockstar/Makita Suzuki's Chad Reed with a 53.015, then Monster Energy Kawasaki's Ryan Villopoto with a 53.292, then Yamaha's Josh Hill (54.086), GEICO Powersports Honda's Kevin Windham (54.257), Honda Red Bull Racing's Andrew Short (54.289), JGR Yamaha's Josh Grant (54.392), Monster Energy Kawasaki's Timmy Ferry (54.454), Honda Red Bull Racing's Davi Millsaps (54.519) and Honda Red Bull Racing's Ivan Tedesco (54.641).
