Doctor's mother storing anything new in drawer (11)
I believe the answer is:
draughtsman
'drawer' is the definition.
(I've seen this before)
'doctor's mother storing anything new' is the wordplay.
'doctor's' becomes 'drs' (abbreviation).
'mother' becomes 'ma' (ma can mean mother).
'storing' is an insertion indicator.
'anything' becomes 'aught' ('aught' means anything).
'new' becomes 'n' (abbreviation as in New Testament NT).
'drs'+'ma'='drsma'
'drsma' going around 'aught' is 'draughtsma'.
'draughtsma'+'n'='DRAUGHTSMAN'
'in' is the link.
(Other definitions for draughtsman that I've seen before include "jumps over others on board" , "Technical plan maker" , "One skilled at drawing" , "potential king" , "Person qualified to produce scale drawings" .)
