'fight' is the definition.
(I know that fight can be written as scuffle)

'les struggling to get a blow in' is the wordplay.
'struggling' indicates anagramming the letters.
'to get a blow' becomes 'cuff' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'les' anagrammed gives 'sle'.
'sle' placed around 'cuff' is 'SCUFFLE'.
