Marvin Emnes has recovered from the knock that forced him off in Saturday's victory over Wigan Athletic.
The matchwinner came off as a precaution at the weekend with a tight hamstring, but having shown no reaction in training on Monday, he is expected to be in the starting line-up for the visit of Cardiff City tomorrow night.
Rovers' options are also boosted by the return of Hope Akpan after the midfielder completed his four-match suspension following his sending off against Sheffield Wednesday last month.
But with the side on a three-match unbeaten run, and with an increasing pool of players to select from, boss Tony Mowbray knows it won't be easy for those returning to force their way back into the starting eleven.
"Marvin Emnes trained today and looked fine," said the head coach.
"I just saw him rubbing his hamstring and I asked him if he was okay but he wasn't sure, and then I decided he was coming off, but as he was coming off he said he was fine.
"Sometimes footballers are not sure what a niggle is so it is better to make that decision. So we sit here today and he is back training today no problem, so as we won the football match and he's still fit, then it was the right decision.
"The squad is getting stronger all the time. Tommie Hoban was involved on the bench at the weekend, Elliott Bennett was back from his suspension, Hope Akpan is now back from his suspension.
"Wes Brown is training, Elliott Ward is training, Corry Evans has been training for the last three or four days and could probably do with a game for the Under-23s but won't be far away. So it is starting to look stronger, it is starting to come together.
"What is good for me is that they aren't just going to fill the squad out, they are players that hope and expect to be able to force their way back into the starting line-up.
"When a team has been winning of course it is difficult for them to force their way into the starting line-up, but it is good that they are on the training ground champing at the bit and looking every inch really good footballers.
"As these games keep coming, I've been here 12 days and we are on our fourth match already. It is Tuesday, it is Saturday, so we have to find a way to utilise everybody to give them game time but not to jeopardise the consistency of the team that has been pretty good over the last week or so."
