Victor, defender (8)
I believe the answer is:
champion
I believe this is a double definition.
'victor' is the first definition.
(I've seen this before)
'defender' is the second definition.
(I know that champion is a type of defender)
(Other definitions for champion that I've seen before include "The first-placed in a competition" , "1st place winner" , "Stick up for" , "Overall winner" , "Fight for" .)
