Dollar does for him! (4)

I believe the answer is:

buck

This clue is a double definition.

'dollar' is the first definition.
(slang)

'for him' is the second definition.

'does' acts as a link.

(Other definitions for buck that I've seen before include "Blood < money" , "Male hare" , "Male beast" , "Male -- something that stops here?" , "Male - resist" .)

I've seen this clue in The Sun.
