The summer music festival says 76-year-old Nobs fell while skiing and underwent surgery at the university hospital in Lausanne, where he has remained unconscious and requires further testing to determine how to proceed.
A statement Monday from the festival said its planning will continue with its secretary general, Mathieu Jaton, assuming Nobs' responsibilities.
Swiss newspaper Le Matin reported Nobs has been in a coma for two weeks since the accident on Christmas Eve, while he was cross-country skiing near his home in the village of Caux, near Montreux, at the eastern end of Lake Geneva.
