Doctor to assess wound (8)
I believe the answer is:
lacerate
'wound' is the definition.
(thesaurus)
'doctor to assess' is the wordplay.
'doctor' becomes 'lace' (I've seen this in other clues).
'to assess' becomes 'rate' (rating is a kind of assessing).
'lace'+'rate'='LACERATE'
(Other definitions for lacerate that I've seen before include "Tear or make deep cuts" , "Tear or cut (flesh) deeply" , "Clear tea (anag.)" , "Injure be tearing, wound roughly" , "Tear roughly, cut jaggedly" .)
