Celtic manager Ronny Deila has told the club's official Twitter account that Dedryck Boyata could be out for up to three weeks, but Stuart Armstrong should be back next week.
Norwegian Deila is under pressure having crashed out of the Champions League and Europa League, whilst his Celtic side also sit level on points with Aberdeen at the top of the Scottish Premiership - but the Bhoys have two games in hand.
This weekend, Celtic take on Partick Thistle at Celtic Park, and the Bhoys will need a win having lost their last home game against Motherwell.
Two players who won't be featuring in that game are defender Dedryck Boyata and midfielder Stuart Armstrong, who have both been ruled out of the game through injury.
Manager Ronny Deila spoke to the press earlier today, and as quoted by the club's official Twitter account, he claimed that summer signing Boyata could be out for up to three weeks in a major blow for the club's backline.
Meanwhile, midfielder Armstrong's injury was described as 'nothing major', and Deila believes that whilst the Scot won't face Partick Thistle, he should be back within in the next week.
RD on injuries: It was a grade one pulled muscle for Dedryck (Boyata) so that’s one to three weeks.— Celtic Football Club (@celticfc) December 31, 2015
RD: With Stuart (Armstrong) it’s nothing major so I don’t think he’ll reach the weekend but should be available next week.— Celtic Football Club (@celticfc) December 31, 2015
How much will Celtic miss Boyata and Armstrong against Partick Thistle?
