Minor injury reduced (3)
I believe the answer is:
cut
This clue is a double definition.
'minor injury' is the first definition.
(I've seen this before)
'reduced' is the second definition.
('cut' can be similar in meaning to 'reduced')
(Other definitions for cut that I've seen before include "Percentage" , "Sever, slice" , "minor injury" , "Reduction; piece of meat" , "Slice, chop" .)
