Organ cut by doctor who's not yet qualified (1-6)
I believe the answer is:
Here is my best explanation:
'who's not yet qualified' is the definition.
'organ cut by doctor' is the subsidiary indication.
'organ' becomes 'liver' (liver is a kind of organ**).
'cut by' is an insertion indicator.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'liver' placed around 'dr' is 'ldriver'.
