Robert Kubica has "very severe injuries", a figure close to the Renault driver revealed on Sunday.

As the motor racing world awaits official information about the Pole's condition after a high speed rally crash, Stephane Samson - referred to as a 'consultant' to Kubica by the German news agency SID - shed some light on his injuries.

"All we know is that Robert's life is not in danger," Samson said. "However, he has very severe injuries to his left hand and left leg, but we don't know anything more about it."

It was earlier rumoured that the 26-year-old, reportedy in a serious condition, has internal injuries, a broken femur, and a badly crushed hand that surgeons are considering amputating.

A detailed medical bulletin is expected shortly.
