Tony Mowbray readily admits that he wasn't aware of the rivalry between Rovers and Burnley, but within minutes of the draw being made he was soon put right.
The Rovers boss watched the draw live as the two Lancashire sides were pitted against each other in the second round of the Carabao Cup and at the time didn't realise the significance.
"First and foremost I was just happy to be at home," Mowbray told iFollow Rovers.
"As far as it being Burnley, people around this building at the training centre have made me aware the rivalry, the close rivalry of it really.
"I got two messages on the night from staff here, but everybody was talking about it the next day of course.
"I have to say living in the north east of England, Suffolk and Scotland most of my life I never would have grasped that Blackburn and Burnley and the geography of how close they were to be honest.
"It is not something that has hit me in the face before of a huge rivalry and yet I can feel it from the people around the building who have lived here all their lives how important this game is to them.
"So like all derbies, and I've been involved in a lot of derbies in the various parts of the country, we'll give it our very best shot and leave no stone unturned in trying to get a result.
"Lets hope, because it is such a big game, a derby game, that however the game is going the fans are supportive of the lads in the blue and white shirts who are trying their best for them."
