Damage from blows or a fire? Cue wall being rebuilt (11,3)
I believe the answer is:
cauliflower ear
'damage from blows' is the definition.
(deformity caused by boxing)
'or a fire? cue wall being rebuilt' is the wordplay.
'being rebuilt' indicates an anagram.
'or'+'a'+'fire'+'cue'+'wall'='orafirecuewall'
'orafirecuewall' with letters rearranged gives 'CAULIFLOWER EAR'.
(Other definitions for cauliflower ear that I've seen before include "Damaged organ" , "damaged appendage" , "result of being battered?" , "Auricular deformation seen in boxers and rugby forwards?" , "Battle-scarred lug" .)
