Volleyball position (6)
I believe the answer is:
setter
'volleyball position' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for setter that I've seen before include "Red - - , dog" , "Everyman" , "Breed of dog - crossword compiler" , "Dog trained to scent game" , "Bird trained to scent game" .)
