Jules Bianchi has been involved in a major crash at the Japanese Grand Prix.
The Frenchman hit a JCB recovery vehicle that was removing Adrian Sutil's stricken Sauber from the circuit.
Both the Safety and Medical car were deployed and he was taken initially to the Medical Centre before being transferred via ambulance to a local hospital with a police escort.
It was confirmed by the FIA Press Officer that Bianchi was not conscious when he was transferred and his current condition is unknown. It was expected that he would've travelled to hospital by air ambulance, however with the inclement weather conditions it was not possible.
A statement was released by the aforementioned Press Officer, Matteo Bonciani: "Driver is not conscious. He's been sent to the hospital by the ambulance. A further update will follow, for now we cannot say anything".
All members of F1Today.net would like to extend their best wishes to Jules Bianchi at this time.
