Michael Schumacher, seven-time Formula 1 world champion, is in "critical condition" after a ski accident, says the French hospital at which he is being treated.
The 44-year-old German "was suffering a serious brain trauma with coma on his arrival" the hospital in the south-east city of Grenoble said in a statement.
Schumacher's management confirmed his critical condition, reports said.
He was skiing off-piste with his son in the Alps when the accident occurred.
Schumacher was wearing a helmet when he fell and hit his head against a rock, Meribel resort director Christophe Gernignon-Lecomte said earlier.
