But the team that wins tomorrow afternoon - if there is a clear winner - will be in the box seat as far as a second-placed finish in National League One is concerned.
Both Halifax and Celtic have been stressing the non-decisive nature of this game all week.
Fax coach Matt Calland certainly believes his side's hunt for the runners up spot will go down to the wire at Post Office Road, Featherstone next Sunday afternoon.
But while the mathematics are not finite, behind closed doors both sides know what is on the line tomorrow.
You only have to look at the respective team selections - Fax hoping against hope that Sean Penkywicz and Shad Royston are fit enough to return and Celtic tipped to give star half back Jace Van Dyke an early comeback - to recognise that.
Given the two sides' final fixtures, Celtic host champions Salford, a Fax win tomorrow is arguably more valuable, especially if they can deny the visitors a bonus point.
That would leave Calland's side three points clear with a superior points difference, leaving Celtic needing a massive turnaround against the Reds and a Fax collapse at Rovers.
That's the dream scenario. The more realistic turn of events is a close-fought nailbiter, just shaded by one team or another, that will see the cliffhanger extend for another seven days.
But the losers will have lost control of their own destiny. And that could be crucial.
