Player's answer to put in credit (5)
I believe the answer is:
actor
'player's' is the definition.
(I've seen this before)
'answer to put in credit' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'put in' is an insertion indicator.
'credit' becomes 'cr'.
'to' placed within 'cr' is 'ctor'.
'a'+'ctor'='ACTOR'
(Other definitions for actor that I've seen before include "Cruise, e.g." , "Films/stage worker" , "One taking part" , "One with role" , "Film star" .)
