Enthralled by Ali's blow artfully done (6,2)

I believe the answer is:

hooked on

'enthralled by' is the definition.
(someone hooked on something is enthralled by it)

'ali's blow artfully done' is the wordplay.
'ali's blow' becomes 'hook' (punch in boxing - Muhammad Ali was a boxer).
'artfully' indicates anagramming the letters (a devious or artful form of the letters).
'done' anagrammed gives 'edon'.
'hook'+'edon'='HOOKED ON'

(Another definition for hooked on that I've seen is " Enthralled".)

I've seen this clue in The Guardian.
