Rugby scuffle (5)
I believe the answer is:
scrum
'rugby scuffle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scrum that I've seen before include "crush" , "Rugby get-together" , "Rugby formation - they get down to it" , "Rugby set-piece" , "Rugby-players crouch here" .)
