Move back match official, one refused by coaches previously (8)
I believe the answer is:
transfer
'move' is the definition.
(I know that move can be written as transfer)
'back match official one refused by coaches previously' is the wordplay.
'back match official' becomes 'fer' (I can't justify this - if you can you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'refused by' is a deletion indicator (some letters are turned away or refused).
'coaches' becomes 'trains' ('train' can be a synonym of 'coach').
'previously' says to put letters next to each other.
'trains' with 'i' taken out is 'trans'.
'fer' put after 'trans' is 'TRANSFER'.
(Other definitions for transfer that I've seen before include "Change to another group or surface" , "Carry over" , "Star fern (anag.)" , "Reassign" , "Hand, move, change, over" .)
