Soft bed for sportsman (6)
I believe the answer is:
player
'for sportsman' is the definition.
(I've seen this before)
'soft bed' is the wordplay.
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'bed' becomes 'layer' (I've seen this before).
'p'+'layer'='PLAYER'
(Other definitions for player that I've seen before include "Important participant" , "Professional musician - team sportsperson" , "Contestant" , "film, on piano" , "Batsman perhaps" .)
