Traveller's hurt before county game (5,4)
I believe the answer is:
marco polo
'traveller's' is the definition.
(I've seen this before)
'hurt before county game' is the wordplay.
'hurt' becomes 'mar' (I've seen this before).
'before' means one lot of letters go next to another.
'county' becomes 'co'.
'game' becomes 'polo' (polo is a kind of game**).
'mar'+'co'+'polo'='MARCO POLO'
(Other definitions for marco polo that I've seen before include "European traveller" , "Venetian explorer of China in 13th/14th centuries" , "Venetian travel writer, who may (or may not) have served Kublai Khan, d. 1324" , "having month taking care of game" , "Historic trader" .)
