Fellow returned, concealed by extra sobriquet (6)

Ross

I believe the answer is:

byname

'sobriquet' is the definition.
(I know that sobriquet can be written as byname)

'fellow returned concealed by extra' is the wordplay.
'fellow' becomes 'man' (fellow can mean a man).
'returned' is a reversal indicator.
'concealed by' means one lot of letters goes inside another.
'extra' becomes 'bye' (cricket term).
'man' backwards is 'nam'.
'nam' placed within 'bye' is 'BYNAME'.

I've seen this clue in The Independent.
