Celtic came out 4-3 winners in a madcap Premiership encounter with Hearts.
James Forrest followed on from his hat-trick against the Jambos' Edinburgh rivals Hibs last weekend to head the Hoops into an early lead, following a bright start from Robbie Neilson's men. It was a historic day as VAR (video assistant referee) was used in a domestic match for the first time at Tynecastle and a lengthy check had to make sure Anthony Ralston's headed effort into the bottom corner didn't stand.
More VAR dismay was to come for Hoops boss Ange Postecoglou, as a foul by Cameron Carter-Vickers was overturned from no foul to penalty, which Lawrence Shankland dispatched, and then Michael Smith's handball in the box was inexplicably not given.
