Conclude activity on field to lure foxes (4,6)
I believe the answer is:
draw stumps
'conclude activity on field' is the definition.
(as in drawing stumps in cricket)
'lure foxes' is the wordplay.
'lure' becomes 'draw' (I've seen this in another clue).
'foxes' becomes 'stumps' (I can't explain this - if you can you should believe this answer much more).
'draw'+'stumps'='DRAW STUMPS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for draw stumps that I've seen before include "End play" , "Stop play" , "Finish (cricket) for the day" .)
