Dammit Michael !! Michael Schumacher in critical condition after skiing accident (CNN) -- Michael Schumacher, the most successful driver in Formula 1 history, is in critical condition after suffering "severe head trauma" in a skiing accident in the French Alps on Sunday, hospital officials said. The 44-year-old German, who retired from the elite motorsport for the second and final time in 2012, fell and hit his head on a rock, said the director of the Meribel resort where Schumacher was skiing. Schumacher was in a coma when he arrived at the University Hospital Center of Grenoble and required immediate brain surgery, hospital officials said in a written statement. Christophe Gernignon-Lecomte initially told CNN affiliate BFM TV that the injury "is not very serious" but the station later reported it to be "severe head trauma," citing police. In a phone interview with CNN, Gernignon-Lecomte said the incident happened just after 11 a.m. local time (1000 GMT) while Schumacher was skiing off-piste (on unmarked slopes) in the mountains of Meribel resort between Georges Bauduis Piste and La Biche Piste. "He was alone and he wore a helmet. He hit his head on a rock," Gernignon-Lecomte said.
