Marc Marquez, fastest in the opening session, crashed in a very fast and serious crash in this practice. He lost the Honda at top speed on the brakes and suffered a huge crash. He was taken away by ambulance to the track medical center where it was later announced that he had "escaped serious injury".
Bradley Smith also suffered a big crash, a highside at good speed. Alarmingly it appeared as if his left hand was caught under the bike as it slid down the track. Smith is being examined by Italian medical professionals but is suspected of breaking a finger, and possibly his wrist.
