Tony Mowbray has given an update on stricken strikers Dominic Samuel, Adam Armstrong and Bradley Dack.
The attacking trio all missed Saturday's 1-0 victory over Brentford having picked up injuries over the past week.
And whilst the Rovers boss has concerns over Samuel, who he fears could be set for a spell on the sidelines, he had more positive news on Dack and Armstrong, who he hopes could be back available for next Sunday's trip to Bristol City.
"Dominic is a concern for us," said Mowbray. "He's going for a second scan.
"I think there's a partial damage on his cruciate knee ligament, but not a complete one.
"So we're going to be without him for a while I think.
"Adam will be short-term I'm pretty sure. We're hoping Adam might be ready for Bristol City.
"Bradley will probably be ready for Bristol City, but we'll make a late call of whether we risk him because there's a two-week break after that and he'll definitely be fine after that.
"So we'll make that call in the week building up to that game, but he will be training leading into Bristol City and we'll just decide how he is."
Mowbray also provided a fitness update on new signing Jack Rodwell, who put pen-to-paper on a one-year deal with the club on Thursday night.
The Rovers boss believes it may take the former Everton and England midfielder a week or two to get fully up to speed, but he was impressed with what he saw from the 27-year-old in training on Friday morning.
"He has to get his boots on and train," added the manager.
"He has to show me that he can do the things that this team does. He has to run and tackle and pass and chase and fight.
"He'll have to do that in training for a week or two before he gets in our squad.
"He trained on Friday and I don't really know what foot he kicks with because he's got amazing composure off both feet.
"Outside of his left foot, he's pinging it 30 yards. Outside of his right foot, he's pinging it 40 yards.
"He's got lovely composure. I don't think anyone should question Jack Rodwell's talent, because he has played for England and Man City and Everton.
"We'll find out about his personality and character and spirit and whether he can become part of this group."
