Being worshipped, boxer, say, lifted up (3)
I believe the answer is:
god
'being' is the definition.
(god is a kind of being)
'boxer say lifted up' is the wordplay.
'boxer say' becomes 'dog' (boxer is a kind of dog).
'lifted up' is a reversal indicator.
'dog' in reverse letter order is 'GOD'.
'worshipped' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
(Other definitions for god that I've seen before include "Deity" , "eg Cupid" , "Superhuman being" , "Pan perhaps" , "Pluto" .)
