Manager Gary Bowyer says Blackburn's defending must improve if they are to make a late push for the play-offs.
Tuesday's 3-3 draw with Brighton, their third consecutive draw, left Rovers seven points behind Reading in sixth.
"We've scored eight goals in the last three games and not won. That's the disappointing thing," said Bowyer.
"We've got to get back to the mentality of keeping clean sheets, which we've proved we can do, and piece it all together for the last seven games."
A brace from Jordan Rhodes and another goal from Tom Cairney gave Rovers a 3-2 lead at Ewood Park, before Dale Stephens headed in to ensure the points were shared.
The 42-year-old told told BBC Radio Lancashire: "We've been on the receiving end of what we've done in the last two games. Again, we're talking about a game we should have won."
