Rower finally abandoning country river (4)

I believe the answer is:

ural

'river' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for ural that I've seen before include "Mountain range between Europe and Asia" , "River feeding Caspian Sea" , "River of central Russia" , "Russian river giving name to mountains" , "Asian flower" .)

I've seen this clue in The Times.
