Tony Mowbray insists he will pay Crewe Alexandra the respect they deserve when Rovers head to Cheshire looking to progress in the FA Cup.
But he's wary of the threat the Alex pose and goes into the game with injuries concerns - particularly in the midfield area.
"It terms of injuries, Peter [Whittingham]'s a concern with a calf strain," Tony revealed.
"We'll assess him over the next few weeks, but he's probably out between two to three weeks.
"Corry [Evans]'s injury was an impact one, but there's no damage in terms of muscular or anything like that, we just need the wound to sort itself out. We'll look at him maybe Thursday or Friday to see how he is.
"Willem Tomlinson did a good job at the weekend. It was touch and go between him and [Scott] Wharton about who would get the seventh place on the bench and fortunately it turns out we picked the right one.
"I though Willem enhanced the performance of the team, playing at his maximum and giving us energy.
"He epitomises young players being given their chance. We're looking to pick a balanced team to go to Crewe and give them problems."
Mowbray's experienced enough to know that there's always a chance of a cup upset and is wary of Crewe's threat ahead of the trip south, with Hull City at home, the carrot for both sides.
"We have to be respectful of Crewe, who showed in the first game that they have good players," the boss added.
"We'll pick a team to get through the tie and face a Championship team in the next round."
Kick off at the Alexandra Stadium is at 7.45pm on Tuesday night.
Tickets are available in advance from the Ewood Park ticket office up until 4pm on the day of the game, and you can pay on the day at Crewe if needed.
