Depressed class is humble (9)

I believe the answer is:

downgrade

'is humble' is the definition.
(I've seen this before)

'depressed class' is the wordplay.
'depressed' becomes 'down' (synonyms).
'class' becomes 'grade' (synonyms).
'down'+'grade'='DOWNGRADE'

(Other definitions for downgrade that I've seen before include "Denigrate" , "Relegate" , "humble" , "Reduce to lower level" , "Demote" .)

I've seen this clue in The Sun.
