Gian Piero Gasperini faces yet another challenge with a notable player absent from the squad.
Following injuries to Ferguson and Dybala, the situation has worsened with Leon Bailey also out of action.
The Jamaican winger sustained a muscle strain during the match against AC Milan at San Siro.
Medical examinations have confirmed an injury to his left hamstring, which is expected to keep him out for about two to three weeks.
Bailey will not be included for the trip to Glasgow, where Roma will also be missing Baldanzi, who was left out of the UEFA roster.
This situation further limits the attacking options available to the Giallorossi manager.
