Tony Mowbray has admitted the virus in the Rovers camp is still proving problematic for him ahead of two games in three days.
Charlie Mulgrew missed out on playing at Northampton because of the bug before returning to play his part in the win over Rochdale at Ewood Park on Boxing Day.
But others haven't been so lucky, with Dominic Samuel failing to play a part in both games after picking up the illness.
However, the boss is hopeful of having the striker back for the home clash against Scunthorpe on Saturday, depending on how quick his recovery is.
"There are one or two over the last couple of days who have caught the virus we have had over the last week or so, so we'll see how they recover," Tony told iFollow on Thursday morning.
"Some have shaken it off over one or two days, but some have had it lingering. We'll have to wait and see, but injury wise there hasn't been any major problems, which is a positive.
"The plan is for Dom to train today and get air into his lungs. He'll be low on energy levels but we'll see how he does in the next couple of days.
"We're hopeful he will make an impact for us in the next two games, whether that be from the start or off the bench."
Ben Gladwin still remains sidelined but Mowbray is hopeful of seeing the midfielder back in the squad sooner rather than later.
"Ben's had a recent operation," Tony said.
"It was a minor one and a clean up of his knee and is in the building. We'll assess him over the next few weeks and see what level of success the operation was.
"He's obviously not ready to get his boots on and get back on the grass just yet so soon after his operation.
"Hopefully it's good news and we'll see how he does with his rehabilitation process over the next few weeks."
