Excluded the said poet (6)
I believe the answer is:
barred
'excluded' is the definition.
(I've seen this before)
'the said poet' is the wordplay.
'the said' shows a homophone (sound like).
'poet' becomes 'bard' (bard is a kind of poet).
'bard' is a homophone of 'BARRED'.
(Other definitions for barred that I've seen before include "Precluded, obstructed" , "Refused entry to local pub" , "Refused access to, say pub" , "Wouldn't allow" , "Excluded, blocked" .)
