Rangers boss Gio van Bronckhorst has revealed Borna Barisic is in the mix to face Dundee United at Ibrox on Saturday.
The Croatia international left the action against St Johnstone with 10 minutes to go after feeling unwell, but he returned to training on Friday.
Nathan Patterson replaced him for the final exchanges but Barisic is in the mix to start against United.
But the Rangers manager admits other stars will be looked at before the visit of United with Ryan Jack and Kemar Roofe on the sidelines.
Van Bronckhorst said: "We still have some doubts, we will check them (Saturday), and then we will make decisions of which players to start."
The picture at Tannadice is less clear with Tam Courts' side up against with Covid among their camp, as they aim to secure consecutive league wins over Rangers this season.
