Rangers will be without Ryan Jack ahead of their visit to Tynecastle - but Ryan Kent could return to the squad.
Jack limped out of the Europa League defeat to Young Boys earlier in October while Kent has been sidelined since September.
The winger sustained a hamstring injury in his first appearance following a £7million move from Liverpool.
But he was pictured back among his team-mates in training this week and could feature alongside Jon Flanagan , who's recovered from a hernia problem.
Rangers ' last away clash with Hearts ended in a 3-1 victory for Steven Gerrard's side in April.
