Bridge -- one cad played, church official (10)
I believe the answer is:
archdeacon
'church official' is the definition.
(I've seen this before)
'bridge one cad played' is the wordplay.
'bridge' becomes 'arch' (I've seen this before).
'played' indicates an anagram.
'one'+'cad'='onecad'
'onecad' anagrammed gives 'deacon'.
'arch'+'deacon'='ARCHDEACON'
(Other definitions for archdeacon that I've seen before include "Member of clergy" , "ecclesiastical dignitary" , "Anglican clergyman" , "Senior Christian cleric" , "Church dignitary" .)
