Minor injuries - in fact they sound nothing (5)

I believe the answer is:

nicks

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

'minor injuries in fact they' is the definition.
The definition suggests an adverb but the answer is not.

'sound nothing' is the wordplay.
'sound' indicates a 'sounds like' (homophone) clue.
'nothing' becomes 'nix' (nix can mean nothing).
'nix' is a homophone of 'NICKS'.

Can you help me to learn more?

(Other definitions for nicks that I've seen before include "Slangily steals or notches" , "Pinches (slang)" , "Arrests (slang)" , "Prisons (sl.)" , "Notches - arrests" .)

I've seen this clue in The Globe and Mail.
