Celtic have been dealt a huge injury blow ahead of their upcoming Scottish Premiership clash.

What's the latest?

In recent comments cited by the Glasgow Times, Ange Postecoglou revealed that both Joe Hart and Kyogo Furuhashi missed Celtic's 0-0 draw with St. Mirren on Wednesday evening through injury, before claiming that the duo look unlikely to be available for the Bhoys' trip to St. Johnstone on Boxing Day.

Speaking about why the pair missed the St. Mirren game, the 56-year-old manager said: "All of them were unavailable, none of them were rested. I don't know where that came out. I don't rest players, if they want a rest they can have a rest when they're 45. Everyone who wasn't playing tonight was unavailable. Either suspended or injured so that's the case."

And, when asked whether they could make a return to first-team action on Sunday, Postecoglou continued: "Not sure. We'll see, it's unlikely that anyone will definitely come back into it. There's a couple who might be close but we'll see over the next couple of days how they recover."

Postecoglou will be fuming

Considering just how important both Hart and Kyogo have been for Celtic since their respective arrivals at Parkhead this summer, the news that both players look unlikely to make a return from injury for the St. Johnstone clash is sure to have left Postecoglou fuming.

Indeed, over Kyogo's 13 Premiership appearances, the £1.8m-rated centre-forward has scored eight goals and created four big chances for his teammates, as well as earning an average SofaScore match rating of 7.07.

Meanwhile, over Hart's own 17 league outings, the £1.8m-rated goalkeeper has kept nine clean sheets and made an average of 1.7 saves per game, with these returns seeing the former England international average a SofaScore match rating of 6.95.

As such, should Celtic indeed be without the duo once again on Sunday afternoon, it would undoubtedly reduce Postecoglou's chances of taking all three points from the fixture, with anything but a win being rather disastrous for the Hoops' title chances this season - as Wednesday's draw with St. Mirren left the Bhoys six points adrift of the current Premiership leaders.
