Rematch (6)
I believe the answer is:
replay
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">rematch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that rematch can be written as replay)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for replay that I've seen before include "Hold match again" , "Repeated match" , "second game" , "Repeat recording of part of game" , "Match held again" .)
