Celtic 2-0 Hearts: Have your say
Celtic continued their 100% start to the season as the champions and Hearts experienced contrasting fortunes with VAR.
The visitors had a first-half penalty award overturned after Lawrence Shankland's header came off Liam Scales' arm.
And, after the break, Nicolas Kuhn's cross hit James Penrice's hand and the review resulted in record signing Arne Engels scoring his first Celtic goal from the spot.
Luke McCowan also opened his Celtic account with a late strike, confirming Hearts slipped a point adrift at the bottom of the Scottish Premiership.
