Celtic midfielder Ryan Christie is out for the rest of the season after undergoing surgery on multiple facial fractures sustained in last week's William Hill Scottish Cup semi-final win over Aberdeen.
It means Neil Lennon now faces a dilemma as to how he reshapes his midfield ahead of the weekend's clash against Hibs.
Christie played at the forefront of the Celtic midfield's central three against the Dons so Tom Rogic could come in as a direct replacement or Olivier Ntcham could come in with Callum McGregor shunted forward.
Defender Jack Hendry will also miss the Premiership trip to Easter Road on Sunday and the rest of the campaign with a torn hamstring.
Dedryck Boyata (hamstring), Craig Gordon, Eboue Kouassi and Daniel Arzani (all knee) remain out and Leigh Griffiths is working his way back from personal issues. Vakoun Bayo (hamstring) is also out.
