Bearer of the sick brick (9)
I believe the answer is:
stretcher
This clue could be a double definition.
'bearer' is the first definition.
(thesaurus)
'sick brick' is the second definition.
'stretcher' can be an answer for 'brick' (I've seen this before). I am not sure about the 'sick' bit.
'of the' acts as a link.
Can you help me to learn more?
(Other definitions for stretcher that I've seen before include "Sick or injured person may be carried on one" , "It carries the wounded" , "one yawning?" , "Casualty carrier" , "A brick; a patient transport" .)
