Boxers? Nancies' pants (7)

I believe the answer is:

canines

'boxers?' is the definition.
(boxer is a kind of canine)

'nancies' pants' is the wordplay.
'pants' indicates an anagram (UK informal term for 'nonsense' or 'rubbish').
'nancies' is an anagram of 'CANINES'.

(Another definition for canines that I've seen is " Dogs -- teeth".)

I've seen this clue in The Independent.
