Dedryck Boyata is facing the cold shoulder from his Celtic team-mates at Lennoxtown.
The defender claimed to be injured last Friday but that verdict was contradicted by Brendan Rodgers before the Champions League defeat from AEK Athens.
While his team-mates were being knocked out of the Champions League Boyata has been receiving treatment for his back injury and posted a video on Instagram.
According to The Sun:
Now Boyata could be ostracised when he turns up at Lennoxtown.
It is understood several team-mates feel badly let down by his refusal to travel to Greece amid a transfer row.
The Hoops squad place great stock on a strong spirit and team ethic and there looks to be no way back for Boyata.
Celtic rejected an offer of £9m from Fulham for the defender shortly before the transfer deadline with Boyata expected to play against Hearts and AEK Athens.
Things took a turn for the worse on Friday when the defender phoned in unwell with his agent turning up at Lennoxtown demanding to speak to Brendan Rodgers.
Sevilla have been linked with a move for the defender with just two weeks left until the transfer window closes with Celtic keen to conclude a deal with Boyata out of contract next summer.
