Just time for game, maybe (5)
I believe the answer is:
event
'game maybe' is the definition.
'just time' is the wordplay.
'just' becomes 'even'.
'time' becomes 't' (abbreviation).
'even'+'t'='EVENT'
'for' acts as a link.
(Other definitions for event that I've seen before include "Incident - final outcome" , "Item in sports programme" , "Fixture" , "long jump, say" , "400 metres?" .)
