Debarred (8)
I believe the answer is:
excluded
'debarred' is the definition.
('exclude' can be a synonym of 'debar')
This is the entire clue.
(Other definitions for excluded that I've seen before include "Kept out from place or group" , "Ruled out" , "Left out" , "Denied access" , "'Debarred, shut out (8)'" .)
