Depressed sportsman (4)
I believe the answer is:
blue
This clue is a double definition.
'depressed' is the first definition.
(I've seen this in another clue)
'sportsman' is the second definition.
(I've seen this before)
(Other definitions for blue that I've seen before include "sportsperson" , "Dirty" , "Sky-coloured" , "Miserable; waste (money)" , "Naughty < sportsman" .)
