Kazuki Nakajima will sit out the rest of this weekends WEC event at Spa Francorchamps after a heavy crash in Free Practice this morning. Nakajima collided with Oliver Jarvis' Audi during the First Free Practice session this morning after an LMP2 car pulled out of Nakajima's path on the Kemmel Straight, with Nakajima running into the back of the Audi which was hidden by spray in the damp conditions. The teams director, Rob Leupen, has said that "the impact was quite significant and he cannot race because he needs more tests." Leupen also revealed that the #1 car will not run in Second Free Practice as "the monocoque is badly damaged". Audi meanwhile is confident that it can repair their car in time for Jarvis, Lucas di Grassi and Loic Duval to take to the track again later today. Nakajima is currently undergoing tests in hospital in Verviers after complaining of back pain shortly after the incident. UPDATE: It has since been confirmed that Nakajima has fractured a vertebra in the accident. He was quote as saying that his "x-ray shows a fracture in one of my vertebra. It’s unbelievably disappointing but there’s nothing I can do now; I will just focus on coming back as soon as possible. There’s not much I can say about the accident. I was on the straight and suddenly through the spray there was a car right in front of me; I had no time to react."
