Official: Scottish FA announcement sparks Celtic meltdown before Hampden clash

At this stage of the season, everything around Celtic carries a little more weight. Results are scrutinised more closely, margins tighten, and even the smallest details begin to feel decisive.

A narrow 1–0 victory over St Mirren at Parkhead ticked the necessary box, but it did little to ease the underlying tension. If anything, it reinforced the sense that things are not quite as comfortable as they might appear.

Now, only days on, the same opponents stand in Celtic’s path once again — but this time with no margin for error.

Hampden Park awaits.

Celtic approach their Scottish Cup semi-final fully aware of the stakes. League form allows room for recovery; knockout football does not. One lapse, one moment, can alter the trajectory of an entire campaign. That reality alone lends this encounter its edge.

St Mirren, for their part, have already demonstrated their ability to trouble the champions. Three of Celtic’s victories over them this season have been decided by a single goal, while a 3–1 defeat at Hampden in December remains a pointed reminder of how quickly fortunes can shift.

That result has not been forgotten.

Attention will naturally fall on team selection, tactical approach and execution, but another element has quietly entered the conversation. The Scottish FA has confirmed that Matthew MacDermid will referee Sunday’s semi-final, assisted by Ross Macleod and David Roome, with Kevin Clancy on VAR duty alongside Chris Graham.

On the surface, it is a routine appointment. Yet it is unlikely to pass without comment.

MacDermid has overseen three Celtic matches this season — a defeat at Dundee, a win over Livingston, and a 2–1 loss to Hibernian at Celtic Park that still prompts debate. On that afternoon, Auston Trusty was sent off, and Liam Scales saw appeals waved away, moments that shaped the outcome.

Such incidents linger.

They form part of the backdrop to a contest already finely poised. Celtic will expect another tight affair, one that demands composure and clinical finishing. They have delivered in such moments before, but they are equally aware of how quickly control can slip.

That uncertainty is what defines this tie — and may ultimately decide it.
