Former heavyweight boxing champion Muhammad Ali has been admitted to hospital with a mild case of pneumonia.
His spokesman Bob Gunnell said the 72-year-old superstar was being treated by his team of doctors.
He added that he was in a stable condition at the undisclosed hospital.
Mr Gunnell said Ali's prognosis was good because the pneumonia was caught early and a short hospital stay was expected.
Ali, who has Parkinson's disease, appeared in public in September at a ceremony in his home town of Louisville, Kentucky, for the Muhammad Ali Humanitarian Awards.
