Hurt in match, leaves boxing (3,5)
I believe the answer is:
tea chest
'leaves boxing' is the definition.
(I've seen this before)
'hurt in match' is the wordplay.
'hurt' becomes 'ache' (synonyms).
'in' is an insertion indicator.
'match' becomes 'test' (as in a test match in cricket).
'ache' placed within 'test' is 'TEA-CHEST'.
(Other definitions for tea chest that I've seen before include "case for move" , "Leaves boxing" , "Box for Earl Grey, perhaps?" , "Crate (much used in moving house)" , "Container used in removals" .)
