Motherwell have managed to fend off the bug that hit Fir Park last week as they prepare for the visit of Rangers on Sunday.
The Swedish defender is waiting for the results of a scan on the foot injury he suffered the Betfred Cup final defeat to Celtic to determine how long he will be out of action.
Steven Davis (foot) is also a doubt for the Fir Park clash but George Edmundson should have recovered from a bout of illness in time to be available to face the Steelmen while Jordan Jones is closing in on a return from a knee injury.
Motherwell provisional squad: Gillespie, Tait, Carroll, Grimshaw, Mugabi, Hartley, Gallagher, Donnelly, O'Hara, Maguire, Polworth, Campbell, Seedorf, Hylton, Long, Cole, Scott, Carson.
Rangers provisional squad: McGregor, Flanagan, Tavernier, Halliday, Barisic, Edmundson, Goldson, Katic, Jack, Aribo, Kamara, King, Arfield, Barker, Jones, Kent, Ojo, Defoe, Morelos, Stewart, Murphy, Foderingham.
