Fan missing large part of cricket match (4)
I believe the answer is:
over
'part of cricket match' is the definition.
(a cricket match is made up of overs)
'fan missing large' is the wordplay.
'fan' becomes 'lover' (synonyms).
'missing' suggests deleting specific letters.
'large' becomes 'L' (eg in clothes sizes).
'lover' with 'l' taken out is 'OVER'.
(Other definitions for over that I've seen before include "Finished - across - in excess" , "Round of six bowls in cricket - then it's finished" , "Unit of test" , "remaining" , "Rouond of six bowls in cricket" .)
