The condition of boxing great Muhammad Ali has “vastly improved” since he was hospitalized over the weekend with pneumonia, his spokesperson said Monday.

The legend was admitted to an undisclosed U.S. hospital on Saturday with a “mild” case of pneumonia.

The 72-year-old, who suffers from Parkinson’s disease, is expected to be discharged soon, according to a statement from his spokesman Bob Gunnell.

“The Ali family continues to request privacy and appreciates all of the prayers and well wishes,” read the statement.

Originally Cassius Marcellus Clay, Jr., he took the name Muhammad Ali in 1964 after converting to Islam.

Ali was the first boxer to win the world heavyweight championship on three separate occasions, successfully defending the title 19 times.
