Rovers boss delighted with the improvement shown by the players but devastated to lose the match at the death.
Despite losing to a last-gasp winner at Bolton Wanderers on Tuesday evening, boss Michael Appleton was delighted with the performance.
After Saturday's loss to Peterborough United the manager called for an improved showing at the Reebok and although Rovers suffered the same fate, albeit cruelly, Appleton felt that the display was much more of what he was looking for.
"To lose the goal in the manner that we did and as late as we did was disappointing," said the manager after the game.
"But, and it is a big but for once, I was absolutely delighted with the players tonight.
"I thought their commitment, effort and desire to go about their business was fantastic.
"To be honest with you it is pretty much everything that I'm about as a person, let alone a manager. When I go into something I go into it wholeheartedly and my players did exactly the same tonight.
"I'll be surprised if there were any Blackburn fans who turned up tonight who would disagree with me.
"Going into the latter stages I thought we were the ones who were going to nick it. We had three or four decent opportunities.
"But it wasn't to be, they are on a rich vein of form at the minute and sometimes you have those purple patches that they are going through.
"I was delighted with the effort and commitment, and we showed a bit of quality at times and hopefully we'll show that in the game on Sunday."
