Looks like you can get Premier Sports for a month. I didn't go much further in case I'd subscribed. 😂

In fact just went onto St.mirren TV and it says it has the match although not sure if the little symbol by the coverage starts means audio only  

think you can pay for premier sports for the match, no mention of saints tv at the moment. Worst case if he has a firestick he can put a dodgy app on it if you know someone who you can buy a login off
