Narrowly miss scoring with attack on legal profession (3,3,3)
I believe the answer is:
hit the bar
'narrowly miss scoring' is the definition.
(I've seen this before)
'attack on legal profession' is the wordplay.
'attack' becomes 'hit' (hitting is a kind of attacking).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'legal profession' becomes 'the bar' (I've seen this in another clue).
'hit'+'thebar'='HIT THE BAR'
'with' acts as a link.
(Other definitions for hit the bar that I've seen before include "go for a drink!" , "Narrowly miss scoring" .)
