The 74-year-old suffers from Parkinson's Disease but according to reports, they are only expecting a brief hospital stay. He was hospitalised twice in a number of weeks at the start of 2015 when he was found unresponsive at his home in Scottsdale, Arizona.

Ali held the heavyweight title for three spells with the first coming when he was just 22 years old. He beat Sonny Liston in 1964 and was stripped of his title due to not making himself available for army service during the war in Vietnam. 

He sat out for three years and made his comeback in 1970 and regained his title in 1974 when he beat George Foreman in the Rumble in the Jungle in Zaire. 

Ali made an ill-informed comeback against Larry Holmes in 1979 and was diagnosed with Parkinson's in 1984. He is wiedely regarded as one of the finest boxers of all time and one of the greatest sportsmen ever.
