Sport over following result (4)
I believe the answer is:
sumo
'sport' is the definition.
(I know that sumo is a type of sport)
'over following result' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'following' is a charade indicator (letters next to each other).
'result' becomes 'sum' (I've seen this in another clue).
'o' put after 'sum' is 'SUMO'.
(Other definitions for sumo that I've seen before include "Japanese wrestling with big fat men" , "Large Japanese wrestler" , "Grappling" , "one of the martial arts" , "Style of traditional Japanese wrestling" .)
