Rovers will be without Danny Graham and Matt Grimes for Sunday's FA Cup tie at West Ham.
The on-loan duo are cup-tied having played in this season's competition already for Sunderland and Swansea City respectively.
Aside from those two being absent, boss Paul Lambert is expected to have a similar squad to the one that defeated Fulham on Tuesday night as whilst Lee Williamson, Danny Guthrie, Jason Lowe and Nathan Delfouneso are all making good progress in their rehabilitation from injury, none will be ready in time for the match at Ewood.
The manager will also have next Wednesday's league clash against Derby County in mind when selecting the team to face the Hammers.
"We aren't too bad, but we do have another game on Wednesday so that is something that we've got to look at," said Lambert on Thursday.
"We've got a lot of important games coming up so we need to see how everybody is feeling and try to pick a team that will win.
"We do need to watch for our own sakes, that is why this game is a bonus game for us, but also we have a huge game on Wednesday night.
"The amount of games that we've got coming up is massive."
Fans who haven't yet purchased their tickets for Sunday's match are advised to get them well in advance of the 2.00pm kick-off as large queues at the ticket office are anticipated.
