 The move was announced in a two-sentence statement from daughter Melissa Rivers, who flew in from California immediately after her 81-year-old mother’s Aug. 28 hospitalization. 
 
 “My mother...is being kept comfortable. Thank you for your continued support,” read the statement issued as Joan Rivers continued her fight for life at Mount Sinai Hospital for a seventh day. 
 
 While Melissa Rivers said nothing more about the move, doctors speculated it could signify her celebrated wisecracking mom was no longer receiving as much medical treatment. 
 
 “If she is off all life support and in a private room, and resting comfortably, it’s possible the family is waiting for nature to take its course,” said an emergency medicine doctor at a prominent New York hospital. 
 
 Rivers went on life support last weekend, and was placed in a medical coma prior to that. 
 
 Dr. Wendy Edwards, director of palliative medicine at Lenox Hill Hospital, said doctors and the Rivers family were likely trying to balance treatment and quality of life. 
 
 “When we say making people comfortable, it could just mean to stop doing things that add to discomfort,” said Edwards. 
 
 “Taking blood, frequently taking vital signs, taking them for X-rays — these things could add to a patient’s distress.

 Sources told the Daily News that the best-case scenario at this point included months of rehabilitation that would keep the perpetually busy entertainer sidelined. 
 
 And a source close to the family had earlier told The News that legal action was possible against the Upper East Side clinic where Rivers nearly died during a routine throat procedure. 
 
 Doctors were trying to determine the extent of any brain damage suffered during the time when Rivers couldn’t breathe. 
 
 Melissa Rivers had earlier said that family and friends were “keeping our fingers crossed” that her mother could bounce back from her medical woes.
