Crossword Genius

Bones of fish from the south (3)

Ross

I believe the answer is:

doc

'bones' is the definition.
(I've seen this before)

'fish from the south' is the wordplay.
'fish' becomes 'cod' (type of fish).
'from the south' is a reversal indicator (in a down clue, letters go up).
'cod' backwards is 'DOC'.

'of' is the link.

(Other definitions for doc that I've seen before include "Fox perhaps" , "Main dish" , "Medic (colloq.)" , "Quack" , "Consultant" .)

I've seen this clue in The Times.
