Expected large fight (4)
I believe the answer is:
duel
'fight' is the definition.
(duel is a kind of fight)
'expected large' is the wordplay.
'expected' becomes 'due' (I've seen this before).
'large' becomes 'l'.
'due'+'l'='DUEL'
(Other definitions for duel that I've seen before include "Combat between two people in matter of honour" , "Combat to settle a row" , "Fight over a point of honour" , "honourable affair" , "Prearranged engagement" .)
