The 44-year-old German suffered a "serious brain trauma with coma on his
arrival, which required an immediate neurosurgical operation,"
according to a hospital in the French city of Grenoble.
Schumacher was wearing a helmet when he reportedly hit his head on a rock while skiing in the French Alps.
He was airlifted off the mountain following the accident in the resort of Meribel, in the popular Three Valleys area.
The sports star was skiing with his 14-year-old son and some friends when the accident occurred.
Schumacher's agent, Sabine Kehm, said: ''Michael fell on his head during a private ski trip in the French Alps.
"He was hospitalised and is receiving medical care. We ask for your
understanding that we cannot give a running commentary on his state of
health.
"He was wearing a helmet and was not alone.''
