Legendary heavyweight champion and social icon Muhammad Ali has died, a family spokesman said late Friday in a statement.
He was 74.
Ali had been hospitalized in the Phoenix area this week with respiratory issues. The Paradise Valley Police Department told ABC News that an emergency medical services call was made from Ali's address in the Phoenix area on Tuesday, and the Phoenix Fire Department confirmed it responded to a call for mutual aid for a 74-year-old male with respiratory issues at that time.
Retired from boxing since 1981, Ali had battled Parkinson's disease for decades.
