Club's bill raised (3)
I believe the answer is:
Here is my best explanation:
'club's' is the definition.
(bat is a kind of club)
'bill raised' is the subsidiary indication.
'bill' becomes 'tab' (tab is a kind of bill).
'raised' is a reversal indicator.
'tab' written backwards gives 'bat'.
(Other definitions for bat that I've seen before include "Cricketer; mammal", "Flying mammal", "Flutter (eyelids)", "A small flying mammal", "Small flying mammal - like 11 Across", "Night flier", "Nocturnal mouselike mammal", "Nocturnal animal - racket", "Vampire - -" and "A mammal; a club".)
