Rangers captain James Tavernier and frontman Jermain Defoe are injury doubts for Sunday's Ibrox clash with Aberdeen.
Right-back Tavernier jarred a knee in training on Thursday while veteran striker Defoe is struggling with muscle tightness, although boss Steven Gerrard is hopeful both will pull through.
Top-scorer Alfredo Morelos serves the final leg of his four-game ban but Ryan Kent returns from the suspension he received after last month's Old Firm clash.
Graham Dorrans could make his return from a long-term knee injury before the end of the season but Jamie Murphy will have to wait until next campaign for his own comeback.
Provisional squad : McGregor, Tavernier, Halliday, Barisic, Flanagan, Goldson, Katic, Worrall, McCrorie, Kamara, Jack, Arfield, Coulibaly, Davis, Candeias, Kent, Defoe, Lafferty, McAuley, Grezda, Foderingham.
