Boxer who said, "It's hard to be humble when you're as great as I am" (3)

I believe the answer is:

ali

(Other definitions for ali that I've seen before include "Muhammad ___ (or MacGraw?)" , "Muhammad's son-in-law" , "Dickens novel" , "Muhammad --, US boxer" , "Ring' specialist" .)

I've seen this clue in the LA Times.
