Check the figure possibly broadcast (4)
I believe the answer is:
seed
'broadcast' is the definition.
(I know that broadcast is a more specific form of seed)
'check the figure' is the wordplay.
'check' becomes 'see' (synonyms).
'the figure' becomes 'd' (I've seen this in other clues).
'see'+'d'='SEED'
'possibly' is the link.
(Other definitions for seed that I've seen before include "Germ; top player" , "offspring" , "favourite player" , "Pip for sowing" , "From which things grow" .)
