AP sources: Ali’s hospital stay could pose serious issues (The Associated Press)

Muhammad Ali is hospitalized in the Phoenix area with what two people familiar with his condition say may be more serious problems than his previous hospital stays. The 74-year-old boxing great is fighting respiratory issues that are complicated by the Parkinson’s that he was diagnosed with in the 1980s, the people told The Associated Press on Thursday. The two spoke separately in describing Ali’s condition that they say is concerning to family members.
