Ruled out cricketer raising glasses (5)
I believe the answer is:
taboo
'ruled out' is the definition.
(I've seen this before)
'cricketer raising glasses' is the wordplay.
'cricketer' becomes 'bat' (batsman).
'raising' says the letters should be written backwards (in a down clue, letters go up).
'glasses' becomes 'OO' (OO looks like spectacles).
'bat' in reverse letter order is 'tab'.
'tab'+'oo'='TABOO'
(Other definitions for taboo that I've seen before include "Not to be touched or used, banned for religious reasons" , "Prohibited, sacred" , "Socially forbidden" , "(Irrational) prohibition" , "Not to be mentioned" .)
