Rovers boss Tony Mowbray says Bradley Dack and Kasey Palmer could both be available for Saturday's game against Brentford, but Adam Armstrong and Dominic Samuel will be sent for scans.
Dack missed Wednesday's 2-2 draw with Reading after picking up a knock to the knee in the 1-0 victory over Hull City, in which he scored the game's only goal.
The influential attacker is expected to be back out on the grass tomorrow and could come into contention for Saturday's game against the Bees providing he comes through the next couple of days' training unscathed.
Palmer was also missing from the midweek match against the Royals, but Mowbray is confident he will be back for the weekend.
"Bradley is not too bad," said the manager. "I just don't want to risk him.
"We could put him on the pitch and he comes off after 15 minutes and then he's out for eight weeks.
"So if it takes a few days or another week, let's see how he is over the next few days and if he's ready for Saturday.
"If he's not ready for Saturday, that's okay. As long as he plays 35-40 games for us this year, then we'll be happy to get that out of him.
"We just need to be careful that we don't push him too hard. He's a very dynamic footballer, so we have to be careful with him.
"Kasey is a player who can play no. 10 or on either side of the three behind the main striker. He was unavailable tonight, but hopefully he'll be ready for the weekend, so that will be a positive for us.
"That said, I thought Craig Conway did really well when he came on and worked hard.
"I think Joe Rothwell is finding his feet now. I think everybody can see what a good player Joe is. We have to find a way to get the best out of him.
"For me, it was all about him getting acclimatized to the physicality required to play in this team - you have to run, you have to get back, you have to tackle and I think he showed that in abundance tonight.
"Let's assess everybody over the next few days and see who we've got for the weekend."
Rovers were dealt a double blow during Wednesday's game, as Armstrong was forced off with an ankle injury just before the break and second-half substitute Samuel also limped out 18 minutes from time.
Mowbray expects both players to undergo scans over the coming days and whilst he hopes Armstrong's injury isn't too serious, he fears Samuel could be set for a spell on the sidelines.
"Adam has got one of these plastic boots over his ankle at the moment, but he did say to me that he thinks the physio is being a bit over-cautious and he thinks he should be alright," added the Rovers boss.
"Whether he means he's alright in the next day or two, or whether he means a week or two, I don't know. Let's wait and see.
"I'm pretty sure he'll be getting some sort of scan or x-ray in the next day or two, but hopefully it's just precautionary and it comes back all clear.
"Dominic I don't know yet. He obviously limped off very gingerly. It's a problem with his knee, I think, so there could potentially be some ligament damage.
"He'll be getting a scan as well I would assume, so fingers crossed it's nothing too serious."
