Championship leader Jorge Lorenzo just took a big highside in first practice. He was flicked over the top coming 'round the very long, slow left that comprises Turn two. It looked like an off-the-throttle crash. He appeared to land on his knees. He sat up and appeared to be holding his right leg. TV has just shown pictures of activity around the medevac helicopter, and rumors say he has damaged his ankle. Rossi finished the session quickest from Stoner with the rest a long way back. Pedrosa and Dovizioso were third and fourth.
