Surrendered, conceded (7)
I believe the answer is:
yielded
This clue is a double definition.
'surrendered' is the first definition.
(I've seen this before)
'conceded' is the second definition.
('yield' can be a synonym of 'concede')
(Other definitions for yielded that I've seen before include "succumbed" , "Generated (financial return)" , "Returned" , "Relinquished" , "Delivered" .)
