Team ban that's not part of the main article (7)
I believe the answer is:
sidebar
'article' is the definition.
(I know that sidebar is a type of news article)
'team ban' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'ban' becomes 'bar' (I've seen this in other clues).
'side'+'bar'='SIDEBAR'
'that's not part of the main' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for sidebar that I've seen before include "Courtroom conference between the lawyers and the judge" , "Explanatory panel" , "South African solicitors" , "Short item throwing light on the main article - braised (anag)" .)
