Who is the referee for Rangers v Hibs and Celtic v St Johnstone in the Premier Sports Cup semi-final? Plus ref for each SPFL Premiership and Championship match

Hampden plays host to two matches fresh from a rocking Scotland international performance and the National Stadium will be packed again on Saturday and Sunday with Celtic meeting St Johnstone on Saturday before Rangers meet Hibs there for the first time since the 2016 Scottish Cup final.

Will Rangers have a new manager in place by then and if so, will he be in the dugout?

That's one question for the weekend, but another being asked across the country will be – who’s the ref?

Here’s a look at the man in the middle for each of the weekend games, in the top two divisions, plus Hibs’ trip to Ross County on Tuesday night.
