Remove the seat for one French doctor in Sale (8)

I believe the answer is:

unsaddle

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

'remove the seat' is the definition.
'unsaddle' can be an answer for 'remove' (unsaddling is a kind of removing). I'm not sure about the 'the seat' bit.

'one french doctor in sale' is the wordplay.
'one french' becomes 'un' ('one' in French).
'doctor' becomes 'dd' (Doctor of Divinity).
'in' is an insertion indicator.
'dd' placed within 'sale' is 'saddle'.
'un'+'saddle'='UNSADDLE'

'for' acts as a link.

Can you help me to learn more?

(Other definitions for unsaddle that I've seen before include "shift from mount" , "get kit off in stable" , "Throw" , "Dislodge a horse rider from their seat" , "What to do after ride" .)

I've seen this clue in the Sydney Morning Herald.
