Damaged and knocked out when caught? (6)
I believe the answer is:
flawed
'damaged' is the definition.
(flawing is a kind of damaging)
'knocked out when caught?' is the wordplay.
'knocked out' becomes 'floored' (I've seen this before).
'when caught?' shows a homophone (sound like) (I've seen 'when caught' mean this).
'floored' is a homophone of 'FLAWED'.
'and' acts as a link.
(Other definitions for flawed that I've seen before include "wrong" , "Blemished; faulty" , "with a hole in it" , "Defective" , "Having blemish or defect" .)
