Teenage driver Sophia Floersch will undergo surgery for a spinal fracture after a spectacular airborne crash at just under 280km/h in the Formula 3 Macau Grand Prix at the weekend.
The 17-year-old German tweeted: "Just wanted to let everybody know that I am fine but will be going into Surgery tomorrow (Monday) morning ... Update soon."
Floersch has a spinal fracture, according to a medical report released by her team, the Netherlands-based Van Amersfoort Racing.
No further details were available.
Video footage showed Floersch appearing to clip Japanese driver Sho Tsuboi's car and flying off the track at high speed on a bend on lap four. Floersch's car then went through a catch fence, hit a structure on the perimeter and dropped to the ground with safety officials immediately on the scene.
In a statement posted on social media, motor sport's governing body FIA said "the driver is conscious and has subsequently been taken to hospital for further evaluation." It added that Tsuboi and "two members of the media and one marshal were also transferred to a local hospital in a conscious state for further evaluation."
Macau is a former Portuguese colony near Hong Kong.
