Not the complete physician? (3)

I believe the answer is:

doc

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

'physician?' is the definition.
('doc' can be a synonym of 'physician')

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for doc that I've seen before include "One of the seven dwarfs" , "Fox perhaps" , "GP (colloq.)" , "Medic (colloq.)" , "scaled-down version of GP" .)

I've seen this clue in the Evening Standard.
