'Human error' in the VAR room led to the technology – or the people operating it at least – missing Isaac Hayden's handball against Watford, which led directly to Fabian Schar's first-half equaliser in Saturday's 1-1 draw.
The Magpies had been trailing since Will Hughes' second minute opener, but a scrappy finish from Schar shortly before the break allowed them to go into the break level, and while there were no real shouts for handball at the time, replays did show that the ball had struck Hayden's arm before making its way to the Swiss defender.
The new handball rule states that, whether intentional or not, if contact between the ball and an attacking player's arm leads directly to a goal, then play should be pulled back.
