He's possibly including rower who's husky (6)
I believe the answer is:
hoarse
'husky' is the definition.
(I know that husky can be written as hoarse)
'he's possibly including rower' is the wordplay.
'possibly' indicates an anagram.
'including' indicates putting letters inside.
'rower' becomes 'oar' (I've seen this in another clue).
'hes' anagrammed gives 'hse'.
'hse' enclosing 'oar' is 'HOARSE'.
'who's' acts as a link.
(Other definitions for hoarse that I've seen before include "(Of voice) rough, harsh" , "Of voice, rasping or gruff" , "Ashore (anag)" , "in need of throat spray?" , "Gravelly" .)
