Boxing great Muhammad Ali was hospitalized at an undisclosed location Saturday due to a mild case of pneumonia, according to reports.

Ali was said to be in "stable condition" Saturday night.

"He was admitted earlier this morning and because the pneumonia was caught early, his prognosis is good with a short hospital stay expected," Ali's spokesman BobGunnell said in a statement, according to ESPN.

The news of Ali's illness came just days after it was learned that Ernie Terrell, like Ali a member of boxing's golden generation, died at the age of 75. Terrell was the recipient of one of Ali's signature "taunts" during his trash-talking days as Ali repeatedly asked Terrell, "what's my name?" after Terrell refused to call the former Cassius Clay, "Ali."
