Tony Mowbray believes tonight's match against Scunthorpe United will be their toughest test of the season so far.
Rovers travel to Glanford Park in good heart following Saturday's 3-0 away win over Rochdale, but the manager knows it will count for nothing if they can't follow it up with another points haul this Tuesday night.
Rovers have found form in front of goal having scored seven in their last two league outings, but Mowbray will happily settle for a scruffy 1-0 victory over a strong Scunthorpe side.
"I find that this is a huge challenge for us this game," admitted the Rovers boss.
"Coming after Saturday and the positive manner of the performance and the result in front of such a large following.
"What we don't really need is a poor performance, an insipid performance and a defeat on a Tuesday.
"We need another performance where it makes people stand up.
"I'd like to think we can go there and grind out another 1-0, score a scruffy goal, put the points in the bag and go back and hopefully find a really positive performance at the weekend at home and just keep rolling on.
"But I do see this as a potential big obstacle in our way this game. I think it is a big game for them. They are still unbeaten, Blackburn Rovers coming to town is a test for them, and one that we have to rise to the challenge and be ready to face it head on."
