Bulletin sees all points supported by players (8)
I believe the answer is:
newscast
'bulletin' is the definition.
(I've seen this before)
'all points supported by players' is the wordplay.
'all points' becomes 'NEWS' (north east west south).
'supported by' is a charade indicator (letters next to each other) (in a down clue, some letters hold up others).
'players' becomes 'cast' (group of actors).
'news'+'cast'='NEWSCAST'
'sees' acts as a link.
(Other definitions for newscast that I've seen before include "media reports" , "Topical programme" , "TV feature maybe" , "TV report of recent events" , "Radio or TV current affairs update" .)
