Injured with a weapon by hothead? (6)
I believe the answer is:
harmed
'injured' is the definition.
(harming is a kind of injuring)
'with a weapon by hothead?' is the wordplay.
'with a weapon' becomes 'armed' (I've seen this before).
'by' is a charade indicator (letters next to each other).
'hothead?' becomes 'h' (head letter of 'hot').
'armed' after 'h' is 'HARMED'.
(Other definitions for harmed that I've seen before include "Hurt" , "Injured or damaged" .)
