Schumacher 'has second operation'
Former F1 world champion is fighting for his life in hospital after skiing accident in French Alps on Sunday.
Michael Schumacher has undergone a second operation following a skiing accident in the French Alps, German and French media have reported.
French doctors in Grenoble will give an update on the condition of the Formula One legend at 10am on Monday.
The 44-year-old German suffered serious brain trauma, was in a coma on arrival and underwent immediate surgery.
He was skiing off-piste with his son in the French Alps on Sunday morning when the accident occurred.
The hospital in Grenoble will issue further information on his condition at 11:00 local time.
Schumacher was wearing a helmet when he fell and hit his head against a rock, his manager Sabine Kehm said.
Germany's Bild tabloid reported that his condition had worsened and surgeons had drilled holes in his skull to reduce the pressure on his brain.
Early reports had said his condition was not life-threatening and he reportedly walked away from the accident complaining only of feeling a bit shaken.
The accident took place in the French ski resort of Meribel.
The resort's director, Christophe Gernignon-Lecomte, said the former champion was attended to by two ski patrollers who requested helicopter evacuation to the nearby valley town of Moutiers.
He was subsequently moved to the bigger facility at Grenoble, in south-east France. His wife Corinna and two children are with him.
