The former world heavyweight champion, now 72, was admitted to a hospital in an undisclosed location on Saturday and is being treated by a team of doctors. He remains in a stable condition.

Ali, who also won an Olympic gold medal in 1960, is expected to recover from the illness and spokesman Bob Gunnell said: "Because the pneumonia was caught early, his prognosis is good with a short hospital stay expected.”

He declined to give any further details of the boxer's condition and stressed that Ali's family was asking for privacy.

The boxing great, who suffers from Parkinson's disease, made a public appearance in September to attend a ceremony in Louisville, Kentucky, for the Muhammad Ali Humanitarian Awards.

A three-time world heavyweight champion, Ali was diagnosed with Parkinson's about three years after he retired from boxing in 1981.
