It was debut weekend for VAR in Scotland with many key decisions coming into focus.
Hearts and Celtic played out a thriller at Tynecastle as Ange Postecoglou's side ran out 4-3 winners on the day. It was a drama filled afternoon in the capital with a number of big talking points for the new technology system to analyse. Hearts were awarded two penalties with one retaken, Anthony Ralston had a goal ruled out and Michael Smith had the Hoops claiming for a spot-kick of their own for a handball. All four key moments were put under Dermot Gallagher's microscope as he delivered opinions on them all.
The former English Premier League whistler also gave his verdict on the red card handed to Livingston at Ibrox as Giovanni van Bronckhorst and Rangers dropped points with John Lundstram rescuing a share of the spoils in added time. The 1-1 draw leaves them trailing Celtic by four points in the race for the Premiership title.
