Goalposts (8)
I believe the answer is:
uprights
'goalposts' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for uprights that I've seen before include "Vertical posts as for rugby match" , "Vertical posts or stakes" , "goalposts?" , "Vertical posts as in rugby goal" , "Vertical posts in rugby pitch" .)
