The ring is concealed by Karen Andrews (5)
I believe the answer is:
arena
'the ring' is the definition.
(ring is a kind of arena or venue)
'concealed by karen andrews' is the wordplay.
'concealed by' indicates a hidden word.
'ARENA' can be found hidden inside 'karen andrews'.
'is' acts as a link.
(Other definitions for arena that I've seen before include "bowl? Possibly" , "Engagement ring" , "Gladiatorial ring" , "Area of endeavour" , "Area surrounded by seating, for sports, etc." .)
