Rangers could be without Scott Wright and Ianis Hagi for their trip to Ross County.
Coach Michael Beale revealed the Ibrox side were managing some fitness issues following a gruelling Europa League win over Alashkert on Thursday.
Steven Gerrard 's team played most of the 90 minutes with 10 men following John Lundstram's first-half red card.
And the squad are feeling the effects of a punishing night at Ibrox.
Rangers travel to Dingwall looking to kickstart their Premiership campaign but Gerrard may have to choose carefully with a return Euro tie in Armenia in midweek followed by a massive derby clash with Celtic.
Kemar Roofe and Glen Kamara will return to the squad having both been suspended in midweek, but Fashion Sakala is still nursing a groin injury.
Hagi and Wright have been assessed over the past few days and a final call will be made ahead of kick-off.
Long-term absentees Ryan Jack and Nikola Katic remain on the road to recovery but are not yet ready for first-team action.
