Not running; away (3)
I believe the answer is:
off
This clue is a double definition.
'not running' is the first definition.
(I've seen this in another clue)
'away' is the second definition.
(I know that away can be written as off)
(Other definitions for off that I've seen before include "below par" , "Away, or no longer on the menu perhaps" , "Fielding side" , "Discontinued" , "Away, substandard" .)
