MotoGP surgeon Dr. Xavier Mir says Jorge Lorenzo will need further scans to ensure he did not suffer any injury beyond his collarbone break in his violent Assen crash.
The reigning MotoGP champion flew over the front his Yamaha when he hit standing water at high speed during second practice for the Dutch Grand Prix. Lorenzo was swiftly diagnosed with a fractured left collarbone and will miss this weekend's Assen race.
Dr. Mir said an initial neurological exam had been positive, but remained cautious over further injuries appearing.
"Jorge has a high inertia trauma but results are normal from initial neurological examination," he said. "We will move to Assen to make head and chest scans and also an abdominal exploration.
"Our first diagnosis revealed that there is a left clavicle fracture with a slight shift that will need surgery to repair the bone. This injury is in the background while we rule out any other major injury that may become apparent within 24 hours.
"These kind of impacts at more than 200kph need some time for the body to recover to be able to discard any other major injuries. In principle tomorrow he can travel and within 48 hours he will be operable."
After Assen MotoGP has a two-week break before back to back races at the Sachsenring and Monterey. Lorenzo is currently seven points behind leader Dani Pedrosa in the championship.
