Ali, 72, is widely considered the greatest fighter in boxing history. In 61 fights, he finished 56-5 with 37 knockouts. Ali also won the heavyweight crown three times, the first boxer to do so. Born Cassius Marcellus Clay, Jr., he changed his name to Muhammad Ali after joining the Nation of Islam.
Ali has battled Parkinson’s for decades. In October, Rahman Ali reportedly said his brother’s health had declined to the point where he was too ill to speak, according to The Courier-Journal. Ali later refuted the reports on Twitter, as did his family’s spokesman.
