Rovers were without Scott Dann and Jordan Rhodes for last night's FA Cup replay with Manchester City as groin and foot injuries sidelined the pair, whilst Paul Robinson didn't reappear after the break after sustaining a hamstring strain.
Speaking on whether Dann and Rhodes could return for the City Ground clash, the manager said: "It will be close but we hope so that is for sure
"Jordan was complaining of the niggle that he's had, we've taken him off in a couple of games but he has responded well to treatment so far this week.
"Scott unfortunately limped out of training on Monday.
"So it'll be close, but we certainly hope the pair will come back."
The manager is hopeful that their quick actions have prevented any serious injury to goalkeeper Paul Robinson.
"We'll pick that up on Thursday and see how he is," added Bowyer. "It was just a precaution at half-time. He felt it slightly so there was no need to risk it after what he has been through over the last couple of months."
