Right-back Brendan Moloney is touch and go with his hamstring injury and will be assessed ahead of kick-off along with striker Steven Davies and Jon Stead, while goalkeepers Dean Gerken and Tom Heaton are both `struggling a little bit' according to the Robins chief.
Meanwhile O'Driscoll has confirmed three youngsters are vying for starts having returned from loan spells.
Wes Burns, Bobby Reid and Joe Bryan, who were borrowed by Forest Green, Oldham and Plymouth respectively, will be included in the squad.
City, without a win since March 9, will look to end their six-year stay at this level on a high against Chris Powell's men.
