Former Formula One driver Michael Schumacher was listed in critical condition following a skiing accident in Grenoble, France, The Associated Press reported.
The seven time racing champion remains in a medically induced coma since being brought into the emergency room at the Grenoble United Hospital Center, chief anesthesiologist Jean-Francois Payen told reporters.
"We cannot predict the future for Michael Schumacher. He is in a critical state in terms of cerebral resuscitation. We are working hour by hour. We can say that his condition is life-threatening," Payen said.
Schumacher and his son were skiing on Sunday morning in the French Alpine resort of Meribel "when he fell and hit the right side of his head on a rock. He was wearing a helmet, but the doctors said it was clearly not sufficient to prevent a serious brain injury," according to The AP.
"Some who had suffered this accident without a helmet would not have made it this far," added Payen.
The Grenoble medical team are reportedly "working to relieve pressure on his brain and have lowered his body temperature to between 93.2 to 95 degrees, as part of the medically induced coma," according to The AP.
Schumacher "was conscious when first responders arrived on the scene, although agitated and in shock, according to the resort. He was airlifted to a local hospital and then later brought to Grenoble," The AP also reported.
"Like millions of Germans, the chancellor and members of the government were extremely dismayed when they heard about Michael Schumacher's serious skiing accident," German Chancellor Angela Merkel's spokesman, Steffen Seibert, said in Berlin.
Schumacher had seven drivers' championships and 91 race wins.
His wife and other family members are by his bedside, according to news reports.
