Cheap wicket taken by Bradman after criticism? (5-4)
I believe the answer is:
knock down
'cheap' is the definition.
(I've seen this before)
'wicket taken by bradman after criticism?' is the wordplay.
'wicket' becomes 'w'.
'taken by' is an insertion indicator.
'bradman' becomes 'don'.
'after' says to put letters next to each other.
'criticism?' becomes 'knock' (knock is a kind of criticism).
'w' inserted inside 'don' is 'down'.
'down' after 'knock' is 'KNOCK-DOWN'.
(Other definitions for knock down that I've seen before include "very low in price" , "Declare (lot) sold" , "aim of Haye, say" , "level" , "Cheap - floor" .)
