Formula One legend Michael Schumacher is in critical condition at a hospital in France after a ski accident in the Alps resort of Meribel, French media reported Monday.
Schumacher, who retired a second time in 2012, fell while skiing off-piste with his son and hit his head on a rock, dpa reported.
The 44-year-old seven-time world champion was wearing a helmet and was reportedly conscious when he was reached by rescuers. He underwent emergency surgery for cranial trauma.
The hospital where he is being treated will hold a press conference on his condition at 1000 GMT.
The German was transported by helicopter to a hospital in Moutiers, where he was diagnosed with a cranial trauma. Le Dauphine Libere said he was then transferred to a clinic in the city of Grenoble.
Two of the men behind his successful Formula One career with Ferrari - Jean Todt, the former team principal, and Ross Brawn, the former technical director - arrived in Grenoble overnight, Sky Sports News HD reported on its Twitter feed.
Todt and Brawn were behind Schumacher's five F1 World Championship victories with Ferrari between 2000 and 2004. Brawn also contributed to Schumacher's World Championship wins at the Benetton team in 1994 and 1995.
Schumacher's German doctor Johannes Peil from the sports clinic in Bad Nauheim also arrived in the south-eastern French city.
