Muhammad Ali, 72, has been hospitalized with pneumonia.

The boxing legend was diagnosed with a "mild case" of the illness and was taken to a medical center in an undisclosed location on Saturday, his rep confirmed in a statement to 'E! News.'

"Muhammad Ali, who suffers from Parkinson's disease, is being treated by his team of doctors and is in stable condition," he said. "He was admitted earlier this morning and because the pneumonia was caught early, his prognosis is good with a short hospital stay expected."

Muhammad — who has appeared in public several times over the past few years — was diagnosed with Parkinson's disease in 1984 when he was 42-years-old.

"He has Parkinson's, he has had it for 30 years and it is a progressive degenerative disease but he does well and is healthy outside the Parkinson's," his daughter Maryum previously told 'BBC Sport.'

The retired athlete "enjoys his life and he is clear-minded," she added.
