Boxing legend Muhammad Ali died on June 3, 2016, after a long battle with Parkinson’s Disease. He was 74 when his body finally gave in to his many ailments.<br /><br />The icon participated in 61 professional fights before his heart failed.<br /><br />While many blamed Ali’s boxing career for his brain disease, Dr. Michael Hunter says in REELZ’s new docuseries, Autopsy: Muhammad Ali, that new evidence shows his fighting had nothing to do with his debilitating illness.<br /><br />In the show teaser, the Autopsy doctor claims he discounted the possibility of Ali’s injury being caused by his boxing. Blood clots, however, could have very well been a consequence of his fighting.<br /><br />“If these travel to the lungs, they can cause a pulmonary embolism, which can result in heart failure and sudden death,” admits Hunter.<br /><br />Autopsy: Muhammad Ali airs Sunday, April 1 at 8:00 ET / PT on REELZ.<br /><br />We pay for juicy info!
