Melee gets papers crumpled, somewhat (5)
I believe the answer is:
scrum
'melee' is the definition.
(I've seen this before)
'gets papers crumpled somewhat' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'SCRUM' is hidden in the letters of 'gets papers crumpled'.
(Other definitions for scrum that I've seen before include "Rugby formation - they get down to it" , "Feature of rugby match" , "Rugby huddle" , "Rugby-players crouch here" , "Melee" .)
