Describing Spud's pulled early is not worth mentioning locally (5,8)
I believe the answer is:
small potatoes
'pulled early is not worth mentioning locally' is the definition.
I can't tell whether this definition defines the answer.
'describing spud's' is the wordplay.
I cannot really see how this works, but
'spud' could be 'potato' ('potato' can be a synonym of 'spud') and 'potato' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for small potatoes that I've seen before include "A greengrocer might sell them" , "piddling" , "insignifant amount" , "Person or items of little worth" .)
