LONDON (AP) — Michael Schumacher’s doctors have started trying to wake up the Formula One great from the medically induced coma he’s been in since a skiing accident last month, his manager said Thursday.

The 45-year-old Schumacher suffered serious head injuries when he fell and hit the right side of his head on a rock in the French resort of Meribel on Dec. 29. The seven-time F1 champion has been in an induced coma in Grenoble University Hospital since then, although his condition stabilized following surgery after initially being described as critical.
