One sportingly replaced? (5)
I believe the answer is:
divot
'one' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for divot that I've seen before include "Loose piece of turf" , "Displaced grass" , "Piece of turf dug out of the fairway by a golf shot" , "Clump taken by a golf swing" , "Piece of turf dislodged by golf club" .)
