Footballers wearing Indian dress for big game trip! (6)
I believe the answer is:
safari
'big game trip' is the definition.
(I've seen this before)
'footballers wearing indian dress' is the wordplay.
'footballers' becomes 'fa' (Football Association abbreviation).
'wearing' is an insertion indicator.
'indian dress' becomes 'sari' (I've seen this before).
'fa' going within 'sari' is 'SAFARI'.
'for' is the link.
(Other definitions for safari that I've seen before include "Hunting expedition (in Africa)" , "Animal-viewing trip" , "As fair as an African expedition" , "Hunting journey" , "Long expedition" .)
