Punter injured leg in door (9)
I believe the answer is:
gondolier
'punter' is the definition.
(I've seen this before)
'injured leg in door' is the wordplay.
'injured' indicates an anagram.
'leg'+'in'+'door'='legindoor'
'legindoor' is an anagram of 'GONDOLIER'.
(Other definitions for gondolier that I've seen before include "Punter" , "Traditional boatman of Venice" , "Venetian waterworker" , "One to move over water" , "Venetian waterman" .)
