Poetic pugilist (3)
I believe the answer is:
ali
'poetic pugilist' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ali that I've seen before include "Egyptian name" , "Muhammad's son-in-law" , ""The Greatest" boxer" , "Cassius Clay became Muhammad ..." , "Muhammad - - , legendary boxer" .)
