Doctors have revealed that Michael Schumacher is "fighting for his life" after being involved in a skiing accident in the French Alps on Sunday.
The 44-year-old was airlifted to hospital after hitting his head on rocks during the incident and remains in a critical condition after requiring immediate neurological treatment on Sunday.
Schumacher's doctor, Professor Payen, told reporters: "We can say that he is fighting for his life. We judge him to be in a very serious situation.
"We cannot tell what the outcome will be yet. We are working hour-by-hour but it's too early to say what is going to happen and to have a prognosis.
"We think that his helmet did help, and without a helmet, he wouldn't be here now. We have very good medical procedures and we did actually treat him very quickly and give him what he needed very quickly."
It had earlier been reported that Schumacher had undergone a second operation overnight, but Payan has revealed that the former German driver had only been operated on once, and that there are currently no plans for further surgery.
