Ape Richie, sporting wig (9)
I believe the answer is:
hairpiece
'wig' is the definition.
(I've seen this before)
'ape richie sporting' is the wordplay.
'sporting' indicates anagramming the letters.
'ape'+'richie'='aperichie'
'aperichie' is an anagram of 'HAIRPIECE'.
(Other definitions for hairpiece that I've seen before include "False addition to existing growth on the head" , "rug" , "Switch, for instance" , "Using switch" , "A wig or switch to supplement scalp covering" .)
