Concede match (5)
I believe the answer is:
agree
I believe this clue is a double definition.
'concede' is the first definition.
(I've seen this before)
'match' is the second definition.
(as in two tallies agreeing or matching)
(Other definitions for agree that I've seen before include "confess?" , "Enjoy view in common" , "concede" , "Consent required" , "'Assent, concur (5)'" .)
