Celtic legend Tom Boyd was left fuming after Liel Abada had a goal chopped off against Livingston when a lengthy VAR check led to an offside call.
Ange Postecoglou's men ran out narrow winners at Celtic Park after a battling performance from David Martindale's men, but in the end the Scottish Premiership leaders surged nine points clear at the top of Rangers. An own goal from Ayo Obileye gave the Hoops the opener before Kyogo Furuhashi found the net to double the advantage with Celtic in cruise control.
However, Livingston refused to give up and landed a lifeline when captain Nicky Devlin found the net just before the break instantly after the strike from the Japan cap. The Lions continued to pester the home side's defence in the second half, but Abada had looked to have netted a third for Celtic when he took advantage of a misplaced Morgan Boyes header.
