Celtic will be without Carl Starfelt for the crucial Europa League group stage showdown with Ferencvaros.
It opens up a starting spot at the back for the likes of Stephen Welsh or Nir Bitton as Ange Postecoglou faces a huge call over his defensive options.
Long-term absentee Christopher Jullien is back in training after recovering from a knee injury and is in the Europa League squad.
However, Postecoglou has stated the defender isn't in the running for a top team return just yet.
Playmaker Tom Rogic is also expected to be out until after the international break, leaving a spot open in the midfield for a reshuffle.
James Forrest made his return to the team against Livingston, and is moving closer to full fitness.
Versatile Josip Juranoivic will likely start at left-back with option Boli Bolingoli not included in the Europa League squad.
Kyogo Furuhashi is also in line for return to the team having been benched for the game against Livingston, with Giorgios Giakoumakis leading the line during the Premiership clash.
