Foul in soccer game (8)
I believe the answer is:
handball
'foul' is the definition.
(type of foul in football)
'soccer game' is the wordplay.
'soccer' becomes 'hand' (I can't justify this - if you can you should believe this answer much more).
'game' becomes 'ball game' (ball game is a kind of game).
'hand'+'ball'='HANDBALL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for handball that I've seen before include "kind of foul" , "Offence from soccer" , "Game played in a walled court" .)
