Striker Giorgos Giakoumakis could make his Celtic debut against Livingston.
Manager Ange Postecoglou has revealed the forward is in line to be involved in his matchday squad for the first time since a transfer deadline day move from VVV-Venlo.
If not Sunday, Postecoglou says, he'll get a run out when Raith Rovers visit Celtic Park in the Premier Sports Cup in midweek.
Giakoumakis stayed in Glasgow to work on his fitness as Celtic were beaten away at Real Betis in the Europa League on Thursday.
Nir Bitton and Liel Abada are available again after missing the group stage opener for religious reasons.
Callum McGregor and James Forrest are not far off fitness as they too sat out the Seville trip, with Postecoglou hoping to make changes at the Tony Macaroni Arena.
Greg Taylor (shoulder), Kyogo Furuhashi (knee), Christopher Jullien (knee), Mikey Johnston (hamstring) and Karamoko Dembele (ankle) are still missing.
Livingston will be without Craig Sibbald after the midfielder had nine stitches in a leg wound.
Sibbald faces several weeks out but Stephane Omeonga has arrived at the club and is eligible to play once his fitness is up to speed.
Jackson Longridge has been struggling with a knock and Sean Kelly (ribs) is unavailable while Jaze Kabia and Jack McMillan remain out with knee injuries.
