Exclude the big-headed one (3)

Ross

I believe the answer is:

ban

I'm a little stuck... Click here to teach me more about this clue!

'exclude' is the definition.
(I've seen this in another clue)

'big-headed one' is the wordplay.
'big-headed' becomes 'b' (this might be a standard abbreviation of which I'm unaware).
'one' becomes 'an' (an apple is one apple).
'b'+'an'='BAN'

'the' is the link.

Can you help me to learn more?

(Other definitions for ban that I've seen before include "Embargo" , "Censor or proscribe" , "Veto" , "outlaw" , "Hungarian governor < to forbid" .)

I've seen this clue in the Evening Standard.
