Celtic could throw Matt O'Riley straight into the team as they travel to face Hearts, with Ange Postecoglou dealing with a number of absences.
The title challengers return to Gorgie on league business for the first time since their defeat on the opening weekend of the Premiership season as they look to keep the heat on Rangers.
They sit four points behind the champions with the derby looming on February 2 and know they can't afford a repeat of that early loss to Hearts, but are dealing with some injury issues.
Captain Callum McGregor is out with a serious facial injury suffered in the Scottish Cup win over Alloa last time out, with Yosuke Ideguchi also set to miss this one with an ankle problem.
Long-term injury casualties Kyogo Furuhashi, David Turnbull and Albian Ajeti are all ruled out with hamstring problems, and international football has had an impact too.
January signing Daizen Maeda is away with Japan, who face China on Thursday, and Tom Rogic has been called up to the Australia squad.
That could see Celtic hand a debut to new boy O'Riley, while Liel Abada should be available despite limping off against Alloa.
Hearts manager Robbie Neilson expects to have John Souttar in his squad.
The defender missed Saturday's cup win over Auchinleck Talbot with an ankle injury after Rangers made a failed bid to take him to Ibrox months before scheduled.
Beni Baningime is in contention to start following a knee problem, while Ben Woodburn is back following a Covid-19 absence. Defender Taylor Moore (thigh) will miss out but could return to face Motherwell on Saturday.
