One headed for sack after abusing terrier (7)

Ross

I believe the answer is:

retirer

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

'one headed for sack' is the definition.
The definition suggests a singular noun which matches the answer.

'abusing terrier' is the wordplay.
'abusing' indicates anagramming the letters (I've seen 'abused' mean this).
'terrier' is an anagram of 'RETIRER'.

'after' is the link.

Can you help me to learn more?
