Tony Mowbray says places in his Rovers squad are "up for grabs" and could make changes against Plymouth on Tuesday night.
Blackburn will be looking to get back to winning ways at Ewood Park after suffering a 1-0 defeat against Oldham at the weekend.
Speaking ahead of tomorrow's match, Mowbray says the setback may allow other players to be given a chance in the side.
“We had a full day yesterday, going through the clips," he said. "We wanted to stimulate the players' brains with quicker, sharper movements.
“Hopefully they pick it up as we go along. You can’t do it out on the pitch too much, they do know it and understand it.
“As I’ve said to the team, the days when we don’t win, it’s very easy for the players who haven’t played to knock on my door and ask for a chance.
“To stay in the team, you’ve got to keep producing, keep scoring goals and find a level where I don’t even think about changing that particular position.
“After the weekend, I think it’s up for grabs for players to get an opportunity to get in the team and try to stay there."
Asked to provide an update on Corry Evans and Paul Downing, who missed Saturday's match, Tony says the pair are nearing a return.
“Corry did train on the Thursday he came back but was a bit sore after so we’ve given him a few days to get some treatment," he added.
“The plan is for him to train on Thursday again this week and if he comes through, he’ll be available for Saturday. Let’s see.
“Paul Downing was on his own with the physios yesterday but really running hard and whacking balls, he’s doing everything required so won’t be far away either.
“Darragh Lenihan’s been a big loss for us too, with his athleticism, speed and power.
"Ryan Nyambe has been an option, but he’s been injured as well. You can’t do anything about that but try to find answers.
“I think it will be pretty much the same group tomorrow. We’ll try to freshen it up, I’ll look at them in training today.
“We’ve studied Plymouth and the problems they’ll try to give us. They’ll feel hard done by lately, but we have to make sure they come out on the wrong side of Tuesday’s result."
