This season, Scott has taken charge of several Celtic matches across domestic competitions, gradually building his experience in high-profile games. One of his earliest Celtic assignments came during the League Cup quarter-final clash against Falkirk at Celtic Park, where he oversaw a commanding 5–2 win for the Hoops.

The match was largely straightforward, though Scott did issue a straight red card to Falkirk’s Michael McKenna for a reckless challenge on Anthony Ralston in the closing stages. His performance in that game was generally well received, with minimal controversy and firm control of proceedings throughout.

Scott was also the man in the middle for Celtic’s emphatic 5–0 Premiership win over Ross County at Parkhead in late November. With Celtic dominating from start to finish, the match required little intervention from the referee, who kept a low profile and allowed play to flow.

More recently, he was in charge of Celtic’s away match against Motherwell at Fir Park in February.

His performances in that and other matches have earned him his biggest assignment so far — taking charge of the Scottish Cup semi-final between Celtic and St Johnstone at Hampden. It’s a strong sign that the SFA trusts him with major games.
