Knocked off game, having urge for food (7,3)
I believe the answer is:
poached egg
'food' is the definition.
(poached egg is a kind of food)
'knocked off game having urge' is the wordplay.
'knocked off game' becomes 'poached' (game can refer to wild animals).
'having' is a charade indicator (letters next to each other).
'urge' becomes 'egg' (I've seen this before).
'poached'+'egg'='POACHED EGG'
'for' acts as a link.
(Other definitions for poached egg that I've seen before include "bit of food" , "snack" , "Shelled food item cooked in boiling water" , "Cooked breakfast (stolen?)" .)
