"The waking-up process has begun and will take until Tuesday," a source close to the family told the News, adding that there are concerns that the incident might leave Rivers confined to a wheelchair.
"We are keeping our fingers crossed," her daughter, Melissa Rivers, said earlier Sunday in a statement, thanking people who have expressed support for the 81-year-old comedian. Rivers on Friday described her mother's condition as serious.
