Champ, caught, fell (4)
I believe the answer is:
chew
'champ' is the definition.
(I've seen this before)
'caught fell' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'fell' becomes 'hew' (I've seen this before).
'c'+'hew'='CHEW'
(Other definitions for chew that I've seen before include "What gossips do to fat" , "Gnaw" , "Treat for dog" , "champ" , "Reflect on" .)
