Winger is wearing coat (6)
I believe the answer is:
siskin
'winger' is the definition.
(siskin is a kind of bird)
'is wearing coat' is the wordplay.
'wearing' is an anagram indicator (wear can mean to become damaged).
'coat' becomes 'skin' (I've seen this before).
'is' anagrammed gives 'si'.
'si'+'skin'='SISKIN'
(Other definitions for siskin that I've seen before include "Little bird" , "Type of bird" , "Greenish songbird related to Goldfinch" , "Small songbird related to the goldfinch" , "Finch akin to canary" .)
