Achievement on field that might involve rabbit (3,5)
I believe the answer is:
hat trick
I believe this is a double definition.
'achievement on field' is the first definition.
(three goals in soccer or three wickets in a row)
'that might involve rabbit' is the second definition.
(conjuror pulling rabbit out of a top hat)
(Other definitions for hat trick that I've seen before include "Three wins in a row" , "Achievement of three successive victories" , "Taking three wickets with consecutive balls" , "Three goals scored in a game or wickets taken with consecutive deliveries by an individual" , "Three gains illustrated by conjurer with headgear" .)
