Still at crease, not bowled: not taken in (7)
I believe the answer is:
uneaten
'not taken in' is the definition.
(take in can mean to eat)
'still at crease not bowled' is the wordplay.
'still at crease' becomes 'unbeaten' (not yet beaten in cricket).
'not' suggests deleting specific letters.
'bowled' becomes 'b' (cricket abbreviation).
'unbeaten' with 'b' taken out is 'UNEATEN'.
(Other definitions for uneaten that I've seen before include "Left on the plate" , "Left after dinner" , "Not taken in" , "Make an outline of" , "still on the table?" .)
