Knocked unconscious, and available for inspection? (4,3)
I believe the answer is:
laid out
This clue is a double definition.
'knocked unconscious' is the first definition.
(someone laid out is unconscious)
'available for inspection?' is the second definition.
(laid out ready to be inspected)
'and' is the link.
(Other definitions for laid out that I've seen before include "Dispatched boxer perhaps" , "prepared for burial" , "Spent" , "Paid" , "boxer risks being this" .)
