One who takes the blame for others (9)
I believe the answer is:
scapegoat
'one who takes the blame for others' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scapegoat that I've seen before include "One taking blame for others" , "One made to take blame" , "One blamed for another's mistakes" , "Whipping boy" , "Aunt Sally" .)
