Following game, lord briefly makes money (5)
I believe the answer is:
rupee
'money' is the definition.
(currency of India)
'following game lord briefly' is the wordplay.
'following' says to put letters next to each other.
'game' becomes 'ru' (rugby union).
'lord' becomes 'peer' (peer is a kind of lord).
'briefly' means to remove the last letter.
'peer' with its last letter removed is 'pee'.
'ru' next to 'pee' is 'RUPEE'.
'makes' acts as a link.
(Other definitions for rupee that I've seen before include "Currency of the subcontinent" , "Currency of India, Pakistan and Bhutan" , "cash" , "low cost in Pakistan?" , "Unit of money in India" .)
