Thugs rip out goalposts? (8)
I believe the answer is:
uprights
'goalposts?' is the definition.
(goalpost is a kind of upright)
'thugs rip out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'thugs'+'rip'='thugsrip'
'thugsrip' with letters rearranged gives 'UPRIGHTS'.
(Other definitions for uprights that I've seen before include "Vertical posts or stakes" , "Vertical posts in rugby pitch" , "Vertical posts as in rugby goal" , "Vertical posts as for rugby match" , "goalposts?" .)
