Players utterly banned? (4)
I believe the answer is:
band
'players' is the definition.
(group playing music)
'utterly banned?' is the wordplay.
'utterly' shows a homophone (sound like) (as uttered).
'banned' is a homophone of 'BAND'.
(Other definitions for band that I've seen before include "Zone; group" , "Music ensemble" , "Ring or musical group (4)" , "troop" , "A collection of musicians in ring" .)
