Update at 3:15 p.m. ET: Ali's Funeral Set For Friday
Muhammad Ali, the man considered the greatest boxer of all time, died late Friday at a hospital in Phoenix at age 74. He was battling respiratory problems.
He died of septic shock related to natural causes, with his family at his bedside, according to family spokesman Bob Gunnell.
Ali inspired millions by standing up for his principles during the volatile 1960s and by always entertaining — in the boxing ring and in front of a microphone.
